Building in such an API would be an "attractive nuisance": the implementation can't support it efficiently, so better not to tempt people into using an inappropriate data structure.

It's for much the same reason that, e.g., a linked list rarely offers an indexing API. That's totally ordered too, but there's no efficient way to find the i'th element for an arbitrary i. You have to start at the beginning, and follow i links in turn to find the i'th.

Same end result for a CPython dict. It doesn't use a linked list, but same thing in the end: it uses a flat vector under the covers, but basically any number of the vector's entries can be "holes". There's no way to jump over holes short of looking at each entry, one at a time. People expect a[i] to take O(1) (constant) time, not O(i) time.

The question in the title pretty much says it all. The catch is that T cannot be restricted.

Here is what I have tried:

ANSWER

Answered 2022-Jan-05 at 18:55

If you want the compiler to make calling toMap() an error if T isn't assignable to [K, V] for some K and V, then in some sense it doesn't matter what the output type is in such a case. It could be Map or Map or anything, as long as the toMap() call is a compiler error. I think you'll end up with a runtime error (you can wade through the spec if you really care) so the function won't return... the "actual" return type is never which can be safely widened to Map or anything you want without causing a type safety issue.

Anyway, to make the compiler error happen, you can give toMap() a this parameter which requires this be of ArrayWrapper<[any, any]> or something equivalent. You could use conditional type inference to manually infer K and V from T:

ANSWER

Answered 2021-Nov-06 at 05:49

This is because macros work on code before the code is compiled. Source code is first parsed to Symbols, literals (integers, floats, strings, etc), or Expr (expressions). At this point, all expressions contain only these three things.** After the macro is done and returns an expression, that expression is compiled into runtime code where more complicated objects like Dicts can exist.

The code below illustrates the difference before and after compiling. Note how 1+5 and Dict() were expressions in the macro body, but is afterward evaluated to an Int64 and a Dict.
