in reply to Automatic CODE tags
I think that a very simple code-detection could
already be sufficient. If the post contains something, which
remotely resembles Perl code, and it dosenīt contain
a single <CODE> tag, then wrap the whole
post in <CODE> tags.
This is very crude, and should be toggled off in the preferences,
but if you are smart enough to realize that you have
user preferences, you already have learned enough about
Perlmonks to know that you can use the TT><CODE>
tags for your Perl code.
