I don't why it shouldn't be possible in a staticly-compiled language, but I've
never seen such a beast either.
But then again most languages are really fascist about this sort of thing.

Yes, Randal please please please write it. I may be too late for me too (but I
doubt it - for one thing I use constructors very much like the one above a lot).
Lots of my colleagues would really benefit from it. Persuading people that OO in
perl is a good thing, isn't exactly easy based on perltoot.

Does that count as encouragement?
