            Different results between clang/gcc and MSVC for templated constructor in base class
            Asked 2022-Feb-06 at 21:41

            I stumbled over the following piece of code. The "DerivedFoo" case produces different results on MSVC than on clang or gcc. Namely, clang 13 and gcc 11.2 call the copy constructor of Foo while MSVC v19.29 calls the templated constructor. I am using C++17.

            Considering the non-derived case ("Foo") where all compilers agree to call the templated constructor, I think that this is a bug in clang and gcc and that MSVC is correct? Or am I interpreting things wrong and clang/gcc are correct? Can anyone shed some light on what might be going on?

            It is correct that the constructor template is generally a better match for the constructor call with argument of type DerivedFoo& or Foo& than the copy constructors are, since it doesn't require a const conversion.

            However, [over.match.funcs.general]/8 essentially (almost) says, in more general wording, that an inherited constructor that would have the form of a move or copy constructor is excluded from overload resolution, even if it is instantiated from a constructor template. Therefore the template constructor will not be considered.

            Therefore the implicit copy constructor of DerivedFoo will be chosen by overload resolution for

            Why is my Haskell function argument required to be of type Bool?
            Asked 2021-Nov-30 at 09:42

            Answered 2021-Nov-30 at 09:42

            Haskell values have types. Each value has a type. One type. It can't be two different types at the same time.

            Thus, since x is returned as the result of if's consequent, the type of the whole if ... then ... else ... expression is the same as x's type.

            An if expression has a type. Thus both its consequent and alternative expression must have that same type, since either of them can be returned, depending on the value of the test. Thus both must have the same type.

            Since x is also used in the test, it must be Bool. Then so must be y.

            Call function to generate the value but without plotting the graph

            I have a function where it is possible to generate a map and a coef_val value, but I would like to know if it is possible to call this same function and get just the generated value, without plotting the graph? One possibility that I know exists is to make a new function, for example, f2, without the plotting part, but I wouldn't want to do it this way. Is there another way?

            You can redirect the plot to a NULL file. Relevant section from help(pdf):
