Nitpick: s[...][..] isn't valid syntax anymore; the correct P6
equivalent is s[...] = qq[..], for reasons that were hashed out on
this list some time ago. However, s/.../../ is still valid.
I'm not in favor of the so-called "short forms" having a different
syntax from the "long forms", and I personally like the current syntax
for both. That said, all's fair if you predeclare: I could see
someone creating a module that allows you to tweak the regex syntax in
a manner similar to what you're proposing, if there's enough of a
demand for it.
