SPUG: Programming diagramming software

[Ivan Heffner]

On the subject of perltidy breaking code, I was fortunate enough to 1)
go to OSCON for the tutorials and 2) go to Damian's "Perl Worst
Practices" session. He walk through SelfGOL
<http://www.perlfoundation.org/perl5/index.cgi?selfgol> which was his
entry in the 3rd Obfuscated Perl Contest. It breaks when you run
perltidy on it, but that has to do with assumptions that perltidy
makes and the horrific style that Damian used. Specifically, he
typeglobbed a subroutine named ';
'. That's "semicolon-newline". As in ";\n"->(). Pertidy assumed the
literal newline in single-quoted string was insignificant and thus
removed it. This is an extreme example but it is an example none the
less.
