I apologise if I'm veering off topic here. I've been thinking about
this since Simon posted this mail and I thought at first that it
was insufficently topical, but now I'm not so sure.

This puzzles me slightly. I work in Java every day, and I like the
language. I think that it often (not always) chooses a good trade-off
between usefulness and purity.

But it's the bit about closures that I don't understand. The only Java
feature that I can think of which could be described as closures is
the way that inner classes can refer to final variables of the outer
class. That is a closure of sorts, but it's *very* limited. You can't
close over variables which are actually *variable*.

(Perl offers real closures, so presumably you don't think that Perl
brought anything to a blue-collar audience. I think you're right,
but I'm not quite sure why. Marketing, or something to do with the
language?)
