Perl and Ruby do something similar with regular expressions, where the character following 'm' or 's' becomes the delimiter for that expression, making 'm/\/some\/path/' identical to 'm!/some/path!'. The delimeter can be 'smart' as well, where the closing delimiter is dependent upon the opening one (in the case of brackets, parentheses and braces) leading to expressions like 'm(/some/path)'. It would be really handy if Clojure had a similar #s!!, #s(), #s//, etc. facility.
