Hello,

Firstly, I'm not an actual D programmer. I'm doing a college
research about D language.

My point here is that I faced the following situation.

With the code above

      void main() {
          fun(1f);
          fun(1);
          fun(1L);
          fun!(long)(1L);
      }

      void fun(T)(T i) {
          writeln(typeid(T));
      }

      void fun(int i) {
          writeln("special => int");
      }

I get the output

      float
      special => int
      special => int
      long

that is, even if I call fun(1L), with long literal, the VRP
decide to use specialized fun(int). Due this, it's needed to
specify that I need to use the generic function (losing
readability).

Said this, I wanted to know if this is a bug or an expected
behavior.

Non-template functions are preferred over template, they have priority 
even when it's done with implicit conversion.

This is the case for C++ as well.

Understood. Then, it's expected. Thank you!
