Use ESM syntax, also use one of these methods before running the file.

1. specify "type":"module" in package.json
2. Or use this flag --input-type=module when running the file
3. Or use .mjs file extension

I think the problem is that you are trying to use the deprecated babel-eslint parser, last updated a year ago, which looks like it doesn't support ES6 modules. Updating to the latest parser seems to work, at least for simple linting.

So, do this:

• In package.json, update the line "babel-eslint": "^10.0.2", to "@babel/eslint-parser": "^7.5.4",. This works with the code above but it may be better to use the latest version, which at the time of writing is 7.16.3.
• Run npm i from a terminal/command prompt in the folder
• In .eslintrc, update the parser line "parser": "babel-eslint", to "parser": "@babel/eslint-parser",
• In .eslintrc, add "requireConfigFile": false, to the parserOptions section (underneath "ecmaVersion": 8,) (I needed this or babel was looking for config files I don't have)
• Run the command to lint a file

Then, for me with just your two configuration files, the error goes away and I get appropriate linting errors.

Adding a rule to use file scoped namespaces in .editorconfig worked for me:

• create an .editorconfig file in the solution directory
• add following line/content below (docs, code - IDE0161)

Example .editorconfig file content:

Yes, as of now, the One Definition Rule in the C++ standard doesn't include enumerators.

However, the "the second a is a redeclaration of the first a" explanation doesn't work too.
From [dcl.enum#nt:enumerator-list] we can know that an enumerator-list is a list of enumerator-definition, so they're all definitions.

To measure the branch you are interested in and particularly the scenario when while loop becomes hot, I've used the following benchmark:

give workflow privillege when created token in GitHub:

Part 1: This looks busted at a glance.

"text" is not a string, it's a literal that is being used to create a temporary std::string object, which is then used to initialize the std::pair. So you'd think it would make sense that the string, which is only needed transiently (i.e only until the std::pair is constructed), is gone by the time it is being referred to.

Part 2: But it shouldn't be busted.

However, temporaries that are created as part of an expression are supposed to be guaranteed to live until the end of the current "full-expression" (simplified: until the semicolon).

That's why the call to codegen2() works fine. A temporary std::string is created, and it stays alive until the call to codegen2() is complete.

Part 3: Yet it is busted, in this case.

So why does the string get destroyed prematurely in codegen1()'s case? The conversion from "text" to std::string does not happen as a sub-expression, but as part of a separate function being called with its own scope.

The constructor of std::pair that is being used here is:

According to the C++17 standard (11.3.6 Default arguments)

9 A default argument is evaluated each time the function is called with no argument for the corresponding parameter. A parameter shall not appear as a potentially-evaluated expression in a default argument. Parameters of a function declared before a default argument are in scope and can hide namespace and class member name

It provides the following example:

As far as standards go, for loop scopes are indeed defined differently in C and in C++. In C they are defined as follows:

6.8.5.3 The for statement

The statement

for ( clause-1 ; expression-2 ; expression-3 ) statement

behaves as follows: ...

with no specific reference given to limitations on variable declarations inside the statement. The top-level description of loops ("iteration statements" in the standard) specifies:

An iteration statement is a block whose scope is a strict subset of the scope of its enclosing block. The loop body is also a block whose scope is a strict subset of the scope of the iteration statement.

as you've hinted in your question, code like:
