Bug 870 – contradictory error messages for templates

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.

The idea with multiple error messages is that the first one is correct, and any that follow should be viewed with suspicion because the compiler attempts to correct the error and move on. Of course, it can guess wrong about what is intended.
