Bug 8598 – [regression 2.059] Calling template function doesn't print instantiated line number

This is an example code that has an error. import std.stdio; import std.algorithm; import std.range; import std.conv; void main() { "123".map(x => x.to!string).join("\n").writeln; // test.d line 8 // ^ lack of '!' } Output: C:\dmd2\src\phobos\std\algorithm.d(367): Error: template std.algorithm.map(fun...) if (fun.length >= 1) is not a function template C:\dmd2\src\phobos\std\algorithm.d(367): Error: template std.algorithm.map(fun...) if (fun.length >= 1) cannot deduce template function from argument types !()(string,void) But, compiler should print second error "... cannot deduce template function from ..." with the position test.d(8). This is a regression of 2.059 which introduced by fixing bug 7768 and pull #839.
