But adding one more parameter gives an error!

Template has no effect simply because I added an parameter with a 
default?!?!?!?

Copying the code for readability and for future generations:

template SomeName(T...)
{
	void SomeName(string file = __FILE__, string line = __LINE__, 
string f = __FUNCTION__)() { pragma(msg, f~";"); }
}

void main()
{
	SomeName!("x");
}

And the error:

/d608/f685.d(8): Error: template SomeName(string file = __FILE__, 
string line = __LINE__, string f = __FUNCTION__)() has no effect

 Template has no effect simply because I added an parameter with 
 a default?!?!?!?

You have a bug in there!!!!!!! __LINE__ is not a string!!?!!?! 
Make it `size_t line = __LINE__` and you're good.......
The error message really doesn't help much, though.

Definitely some compiler logic problems there with the error 
message at least.


What I'd like to see:

pragma(msg) should be immune from "has no effect" errors as it 
does have an observable effect at compile-time.
