Actually perl has a lot of problems too. One of the biggest is that
perl script writers always seem to think like you, in that perl is
consistent across all platforms.
The biggest problems I've seen with perl scripts are when people use
perl extensions that are not on the system. You then have to go find
the extension they use and very few of the perl script writers seem
to be smart enough to put a section at the beginning of their scripts
that define the CPAN location of the particular extensions they are
using. The second biggest problem is perl script writers using
constructs that are valid in Perl 5.6 and later but not valid in
Perl 5.0 I don't know how many times I've wanted to strangle
someone when trying to run a perl script under Perl 5.0 that had
ONE single friggin statement in the entire thousand line script that
isn't valid under 5.0 but is under 5.6 And I've also run across
a number of Perl extensions that won't run under 5.0 as well, even
though the authors are supposed to regression test under 5.0

ksh is consistent across platfroms, of course, you generally have to
compile it for the system your on.
If you cannot work within a limited construct set your not much of a
