playing with templates and aliases, i got

damn:D wrong key..

well... playing with templates and aliased, i got

Internal error: ..\ztc\out.c 1127

in this code:

import std.c.stdio;

template max(T) {
 T max(T a,T b) {
  return a > b ? a : b;
 }
}

template Max(alias A,alias B) {
 typeof(A) Max() {
  return 0; max!(typeof(A))(A,B);
 }
}

int main(char[][] args) {
 int a = 5;
 int b = 10;
 printf("Max(%i,%i) = %i" \n,a,b,Max!(a,b)); //max!(int)(5,10));
 return getch();
}


i'd prefer to have a bether error message:D

btw, code can be reduced by much..

like this:

template Foo(alias A) {
 void Foo() {
 }
}

int main(char[][] args) {
 int a = 5;
 Foo!(a);
 return getch();
}

Looks like the compiler is failing to catch the illegal reference to the local 'a'.

exactly. (but it would be great if it would not be illegal:D)
