Then please declare the template parameters to be delegates:
U muddle( T, U)( T f) {
uint g( int fp){
return cast(uint)( 5* f( fp));
}
auto gP= &g;
return gP;
}
unittest {
import std.stdio;
int x = 3;
int scale( int s) { return x * s; }
auto f= muddle!( int delegate( int), uint delegate( int))( &scale);
writeln( f(7));
}
// no deduction problems
