          Issue ID: 24023
           Summary: Unnecessary module prefix in error message types
           Product: D
           Version: D2
          Hardware: x86_64
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P1
         Component: dmd
          Assignee: nobody@puremagic.com
          Reporter: nick@geany.org

The following code (in callconst.d):

struct X {}

void main()
{
    auto x = const X();
    func(x);
}

void func(ref X);


Produces unnecessary module prefixes in the supplementary error line:

callconst.d(13): Error: function `callconst.func(ref X)` is not callable using
argument types `(const(X))`
callconst.d(13):        cannot pass argument `x` of type `const(callconst.X)`
to parameter `ref callconst.X`

This just adds noise and could be removed.

PR incoming.
