This is EXTREMELY minor, and might not even be worth changing. In any case, I noticed that the range in regexp, the [] thing, only is accepted as a variable if it's between two parentheses. I think it'd be nicer if [] by itself was considered a variable.
VERY minor regexp change

I didn't write the regexp stuff, that comes from the PCRE package. In any case, I wouldn't want to change it because it would break thousands of existing regular expressions. Just imagine all the people who have triggers and aliases with [...] in them at present, and who access the variables (captures) by number. If suddenly the sets also became captures all those numbers would be out.
