           Summary: Local variable as template alias parameter breaks CTFE
           Product: D
           Version: 2.003
          Platform: PC
        OS/Version: Windows
            Status: NEW
          Keywords: rejects-valid
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla digitalmars.com
        ReportedBy: reiner.pope gmail.com


The following code fails to compile with error, "cannot evaluate generate() at
compile time." This error is stopped by declaring x in global scope.

void main()
{
    int x;
    const string text = Gen!(x).generate();
}

template Gen(alias A)
{
    string generate()
    {
        return null;
    }
}

Changed version, since this applied to D1.x as well. Still not fixed in D1.031.
For phobos2, the code now needs to use 'enum' instead of const to trigger the
behaviour:
---
void main()
{
    int x;
    enum string text = Gen!(x).generate();
}

template Gen(alias A)
{
    string generate()
    {
        return null;
    }
}
