Just remove the =>

(m, c) {
  // code here
}


Common mistake from people who worked with LINQ in C#.

That's a function that returns a function.

Perhaps you meant to just remove the => and be left with a 
multi-line function.


I simplified the test codes. I want write mode codes in closure, 
such as:


test(cast(ushort) 1, (m, c) => {
  writeln(m);
  writeln(m);
});

import std.stdio;

void test(ushort market, void delegate(ushort market, char* pc) 
callback)

{
for (auto i = 0; i < 10; i++)
{
callback(cast(ushort) i, cast(char*) null);
}
}

void main()
{
test(cast(ushort) 1, (m, c) => writeln(m));
//test(cast(ushort) 1, (m, c) => { writeln(m); });
test(cast(ushort) 1, (ushort m, char* c) => writeln(m));
//test(cast(ushort) 1, (ushort m, char* c) => { writeln(m); 
});
