Which is horrible. Put the @ at the front:

I agree. (Well, I would, wouldn't I? :-)
But if people really, really hate the idea of the @ symbol as a prefix modifier/sigil, I think that there are some alternatives which also look good. (See my previous post.)
!parameter=expression # bang parameter >parameter=expression ^parameter=expression ~parameter=expression
(but not $parameter, thank you).
I suppose that we could even add yet another overloaded meaning on the asterix:
# with no default, * keeps the old meaning of collecting # extra positional values
*parameter
# with a default, * triggers late-binding
*parameter=expression
I should hate that, I know I should... but I kinda don't.
I'll save you the trouble: I hate that :) As I said in the other post, *param changes the meaning of param itself. If there's any meaning to *param=expr, it should be something like "provide one or more args, but if you provide zero, use this instead". Which seems pretty weird. ChrisA
