As I read S05, a modifier has to occur at the *very* beginning
of a regex (or group) in order to work. In other words, no whitespace
before modifiers in a regex (because whitespace may have some
other meta-syntactic meaning with :sigspace). Thus
token foo {:i a }
works, while
token foo { :i a }
is an error, since the ':' acts as a cut operator that doesn't
have anything to cut.
But I admit that since we've gone to regex/token/rule, then perhaps
leading whitespace prior to a modifier should be ignored. That
probably needs a ruling from p6l or @Larry.
