           Summary: Inconsistency in implicit casting of integral template
                    value parameters
           Product: D
           Version: 1.046
          Platform: x86
        OS/Version: All
            Status: NEW
          Keywords: rejects-valid
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: nobody@puremagic.com
        ReportedBy: komadori@gekkou.co.uk


Given a template T(uint N), int values for N are implicitly cast to uint where
N is used within the template body. However, the instantiation of T!(n)
precedes the coercion of n to uint such that the template instances T!(1) and
T!(1u), and any types defined within them, are distinct. I believe this should
not be the case.

Reproduced with DMD 1.046 under Linux and LDC r1522 under Solaris. Test case and compiler output below:
---
module Test;

struct Test(uint N)
{
  int x;

  Test!(N) f(Test!(N) rhs)
  {
    return Test!(N)(x+rhs.x);
  }
}

void main()
{
  Test!(1) x;
  x.f(x);
}
---
Test.d(16): Error: function Test.Test!(1).Test.f (Test!(1u)) does not match
parameter types (Test!(1))
Test.d(16): Error: cannot implicitly convert expression (b) of type Test!(1) to
Test!(1u)
