Re: std.math conflicts with std.mathspecial

[F i L]

Whoops, forgot "std" before "mathspecial":

   import std.math;
   import std.mathspecial;

   void main()
   {
       writeln(std.mathspecial.erf(0.5));
   }

or you could do:

   import std.math;
   import std.mathspecial : erf;

   void main()
   {
       writeln(erf(0.5));
   }
