I'd say both regular expressions and the corresponding python code can 
be pretty incomprehensible.
Regexes because they're too dense and complex, python code becuase it's 
too lengthy to describe what parts of a string you're after.
I've stumbled upon both 100 char regexes and 25 line python string 
manipulation snippets - both variants taking a while to figure out what 
they do.

...but I guess the design of a new, better, string matching sublanguage 
wasn't the topic here? or am I mistaken?
