           Summary: contradictory error messages for templates
           Product: D
           Version: 1.00
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: minor
          Priority: P3
         Component: DMD
        AssignedTo: bugzilla at digitalmars.com
        ReportedBy: thomas-dloop at kuehne.cn


1  template Templ(alias a) {
2    void Templ(...) {
3    }
4  }
5
6  void main() {
7    int i;
8    Templ(i);
9  }

a.d(8): template a.Templ(alias a) does not match any template declaration
a.d(8): template a.Templ(alias a) cannot deduce template function from argument 
types (int)

The two error messages are contradictory:
1) either there was no match and thus the second error messages is wrong
2) or the second message is correct(though doesn't mention line 2) and the 
first message is incorrect

After rewriting the sample:
1  template Templ2(alias a) {
2    void Templ2(x) {
3    }
4  }
5
6  void main() {
7    int i;
8    Templ2(i);
9  }

Error: identifier 'x' is not defined
Error: x is used as a type
a.d(8): template a.Templ2(alias a) does not match any template declaration
a.d(8): template a.Templ2(alias a) cannot deduce template function from 
argument types (int)

The first two messages are missing the location information.
