Hi All,
   Request your help on the below code, I want to send the 
name of the function ( First and Second) from main as an 
argument to another function(Mid) and the function "Mid" has 
to execute the function(First and Second).

Program:
import std.stdio;

void First (string Ftext) {
writeln("First :", Ftext);
}

void Second (string Stext) {
writeln("Second :", Stext);
}

void Mid( string Fun, string Mtext) {
Fun(Mtext);
}

void main () {
string Ftext = "FTest1";
string Stext = "STest2";
Mid(First, Mtext);
Mid(Second, Stext);
}

From,

Maybe:

import std.stdio;

void Mid(alias Fun)(string Mtext) {
    Fun(Mtext);
}

void main () {
string Ftext = "FTest1";
string Stext = "STest2";
Mid!First(Ftext);
Mid!Second(Stext);
}
