Doh! Right. See, you can tell I haven't used them much lately. I'm the
same way with C. I'll start out writing
C = C + 1;
D = C + 1;
then:
C++;
D = C;
then
D = C++; //or is it D = ++C; ?
I always fall back on plain code but get more comfortable with the idioms
for better (Smalltalk) or worse (C)<s>.

Exactly. or, in Object Pascal,
with Caveman do
begin
Find(Flint);
Gather(Twigs);
Light(Fire);
end;
OK, good, I get the Smalltalk syntax now and like it.<s>
