Seriously though, I think this is a big hole in the DMD support of templates.

It's very annoying to get a compiler message that consists of nothing but:

" error: ATemplateFunction: int does not have a .length property"

Where ATemplateFunction is something like

void ATemplateFunction(ArrayT)(ArrayT  x) {
     auto n = x.length;
     ....
}

Great so I know somewhere in my source code I called ATemplateFunction
with the wrong kind of argument.  The compiler knows where it was that
I made the call, but it just doesn't care to enlighten me.  Very
frustrating.

You can debug DMD's frontend. Or Descent. :-P

(and find bugs in the port, yay!)

Can haz now. Currently looking like so

templerror.d(9): Error: identifier 'wrong' is not defined
templerror.d(12): Error: template instance templerror.bar!(int[][][]) error
instantiating
    instantiatied in templerror.d(12): bar!(int[][])
    instantiatied in templerror.d(3): bar!(int[])
    instantiatied in templerror.d(16): foo!(int)

and triggered by errors and static asserts.

We had a brief slide about them in our Tango Conference talk. I hope it'll
be up eventually... :)

Looks great.
Is there a DMD patch for that somewhere in bugzilla?

I sent it directly to Walter a few months ago, but I'll also attach it to
the enhancement request you just opened.

Excellent!  Thanks.  Here's hoping Walter applies the patch.
