There seems to be a problem when having two function with same 
name but different parameters. Only happend when one of the 
function use templates. Is that a compiler limitation?

this is by design. templates are generic so they can take 
anything(by default), this way shadowing specialized functions 
which is more suitable for certain types.

mmm.. this is strange because for simple types it works fine(i'm 
using dmd 2.064.2). can you show reduced example of this?

Have you tried an updated DMD compiler? I think this was recently 
fixed.

This works fine with v2.064.2

import std.stdio;

class ClassName
{
	final uint registerEvent(T, J)(T x, void delegate(J))
	{
		return 1;
	}

	final uint registerEvent(long, string, int, ulong)
	{
		return 1;
	}
}

void main(string[] args)
{
	auto x = new ClassName();

	writefln("%s", x.registerEvent!(int, int)(1, delegate(int x) 
{}));
	writefln("%s", x.registerEvent(1, "sdsds", 3, 4));
}

On older compilers, you can work around this limitation by adding empty
compile-time parameters to the second function:

	final uint registerEvent()(IPlugin, EventHandler, EventInfo, ulong)
	{ ... }


From what I heard, this limitation has been removed in the latest


compiler.

Thanks, i updated to v2.064.2 and everything works just fine. I 
had this issue long time ago and it was annoying to have multiple 
function with different names.
