1) I'll use Perl for the regex stuff from now on, Perl is obviously built for this.
Actually IIRC Perl *invented* regexes as we know them. The "standard" regex syntax is known as "Perl regex syntax".
2 ) There's More Than One Way To Do It makes debugging hard - i.e. close INFILE; & close (INFILE); are both valid. I like one syntax, cos it's easier to remember.
I don't find it that bad. Ruby does it as well, and it's perfectly readable. It's more or less equivalent as if condition: and if(condition): both being valid in Python.
3) Some stuff is counter-intuitive - $lenOfModList = @moddirList is the Perl equivalent of lenofModList = len(moddirList)
You sure of that? I was under the impression that len(moddirList) in Perl was $moddirList (@moddirList is the list itself).
Also, why doesn't if ( not $d eq "a" && not $d eq "c") evaluate to true for $d = "b" when if (not $d eq "a") evals to true and if ($d ne "a" && $d ne "c") evals true also? What's with that?
This probably has to do with operator precedence. It's been lifted from C, so chances are that && has a higher precedence than eq. Use parentheses.
4) WHAT IS WITH THE STUPID SYMBOLS EVERYWHERE LARRY??!!
I'm not referring to the $ & @, I can see how they could be useful, although with a list -
@dude = (1, 2, 3), to obtain the 2nd value I would expect $d = @dude[1],
not $d = $dude[1], that's counterintuitive also.
This will be fixed in Perl 6. Then again, Perl 6 is supposed to be pure heaven, as the Parrot virtual machine can theoretically be used with any language and is heavily optimized. Python and Ruby with the speed of Perl, and the possibility to interface your code with CPAN modules. That's really cool.
Once Perl 6 is released, of course.
Why is the read/write modifier part of the filename??? Why is it a > ? In my opinion, there's only one place a > sign should be, in an inequality test.
This is consistent with UNIX redirection. ./foo > bar.txt executes the command foo, and redirects its STDOUT to the file bar.txt. ./foo >> bar.txt does the same, but appends to bar.txt instead f overwriting it.
