Sure you can! How about this ...


 import std.stdio;

 int delegate(int) increment;

 void main()
 {
    writefln( increment(1) );
    writefln( incr(2) );
 }

 int incr( int a )
 {
     return a + 1;
 }

 static this()
 {
     increment = delegate int ( int a ) {return incr(a); };
 }

Would that do?

Yeah, I guess you could do that as well.
