It seems you missed one crucial point here: the suggestion to 
import std.conv
*does* happen when invoked as 1.to!string, but *not* when invoked 
as to!string(1). It's already doing what you say is not the most 
useful hint, and failing to give a hint when to!string is invoked 
as a function call.

unittest {
     // template instance to!string template to is not defined
     auto x = to!string(1);

     // no property to for type int, perhaps import std.conv; is 
needed?
     auto y = 1.to!string;
}
