std.traits.ParameterIdentifierTuple bug or not?

[Uranuz]

In my programme I need to get names of function parameters when I 
pass some function reference to template function that does some 
manipulations with it. I have updated my copy of dmd to 2.064, 
because there was a bug in previous versions.

But I still can't implement the stuff that I wanted. I don't know 
is it bug or not, so I asking for help. I'm trying to do 
something like this:
//-------------------
module parameter_identifier_test;

import std.stdio, std.string, std.conv, std.traits, std.typecons;

void someFunc(int[] aaa, string[string] bbb, double ccc)
{
	
	writeln("Some function executed!!!");
}

void test(FunctionT)(FunctionT func)
{
	alias ParameterIdentifierTuple!(FunctionT) ParamNames;
	pragma(msg, ParamNames);  //Gives compilation output: tuple("", 
"", "")
	writeln(ParamNames);  //Gives empty string
}


void main()
{	
	test(&someFunc);
	
}
//------------------------

Is there some other way to get names of parameters in situation 
like this?
