That's very true.  For any serious code that could potentially be read
by someone other than me (which is most of the code I write), I tend
to throw all that syntactic sugar out the window in favor of more
verbose and readable code constructs.  But it's all that syntactic
sugar that allows me to be very expressive and hence more productive
in my day to day use of Perl (single-use scripts, one-liners, etc.).

Inconsistency is only introduced by the programmer, not by the
flexibility of Perl syntax.  There's many ways to do the same thing
(TIMTOWTDI is a main tenet of the language), but if you write code
that uses irregular combinations of the aforementioned syntactic
sugar, then of course the inexperienced Perl programmer will get
confused quickly.

I have to agree there, but it still seems strange to have the compiler
rely on indentation though, especially when no other modern languages
care about this.  I'd prefer not to have my code fail to compile and
run just because I left out some white space somewhere.

Things are always ugly if you're not used to them ;-)  Just as with
indentation in Python, everyone gripes about the object system in
Perl, but it makes sense if you consider the design history of Perl.
OO features were tacked on once it seemed necessary and fashionable to
support OOP.  That's all about to change with Perl 6 though.

What does "better" mean?  I think what you mean is that the syntax for
it is cleaner in Python.  That I would agree with.

Fair enough.  To each his own ;-)  It's obviously important to use
tools that you enjoy working with whenever possible.
