Wow.

The range operator is useful for writing "foreach (1..10)" loops and for
doing slice operations on arrays.
On the broader scale...
No, you cannot assume I've taken any C classes. The time when it was
assumed a Perl programmer already knew another language, particularly C and
shell, has long since past. Perl programmers are Perl programmers.
And a feature is for whatever it turns out to be useful for. Perl is full
of features that were designed for one thing and used for ten others each
of which originally considered to be horrible hacks and later realized to
be nice idoms. Just to make sure we haven't lost sight of that.
You like your C style for loops, personally I find them difficult to read
and wrap my head around, but if that's what you're used to have fun. But
don't restrict the rest of the users based on that. TMTOWTDI and all.
Or did I stumble into python-porters?
