Perl syntax highlighting is imperfect (always, at this point)
I actually ... umm ... believe that "syntax highlighting" appears just as mostly keyword highlighting. There seem to be some other code sites around (haven't noted any URLs, sorry) that show bits of code and hey, it looks like code 'cos every if
is in bright turquoise on dark grey.
Now for serious syntax highlighting like one might like in an editor for actually working on code, I'd agree. I get constantly infuriated with Emacs because it's not making the code 'look right' - and if that's the case then sometimes it's maybe preferable to go with kyle and "don't use it".
But I do often find just the basic keyword signposts useful for quick scans of the code. In which case a very simplistic mapping could be selected at either entry time or rendering time.
