Cute idea, but the reverse of this line:
print fi ('Just another Perl hacker,');
is not what you have written; it's this unfortunate thing:
;)',rekcah lreP rehtona tsuJ'( if tnirp
But the code you have does not rely on those parentheses being there, so you are safe.

Also, you have no space in X__ATAD__, but you have a space in __DATA__ X. I guess the "plain-language" definition of a palindrome does ignore spaces. Presumably that can only make the task easier in Perl..

    Thanks, I didn't notice the inverted parenthesis, obviously. That's what I get for checking manually. I also didn't realize, as this script evolved, that I no longer had use for the parenthesis at all. At one point, adding them was necessary for a successful compile.

    Yes, I went with the rule that whitespace and newlines did not have to match.

[ambrus]: erix: that one actually sucks. these days people should get rid of the old notion that TeX is the only thing you can use for decent mathematics writing, because MS Office and LibreOffice have reached the
[ambrus]: level where people can more easily write as good mathematical papers in them as the people who write bad LaTeX papers usually write.
[ambrus]: Yes, for like the first twenty of its years, TeX was basically the only system that allowed you to write decent maths papers, and C++ and PHP were programming languages that sucked, etc. But times change and people have to accept that.

[Discipulus]: php does not suck anymore?
[ambrus]: Discipulus: I'm not sure, but it certainly doesn't suck as much as it's used to. it's like C++, it sucks because people still recursively learn from twenty year old PHP examples,
[ambrus]: and they try to use the obsolete features that PHP has to support only for compatibility with old scripts. C++ and PHP both have the problem that people can't forget the past, because when they google "PHP" plus the problme they want to solve, they find b
[ambrus]: ad code examples.
[ambrus]: I'm not trying to recommend PHP, but I think it has way too bad a name because of its past.
