Ok, so that's pathological, but this isn't
perl -e 'print -rwx($_)'
Undefined subroutine &main::rwx called at -e line 1.
Just think about all the possible subroutine names you can make out of
the set of chars [rwxoRWXOezsfdlpSbctugkTBMAC]. I don't think we want to
prevent the use of those names by allowing the -XXX syntax without some
special char used as a prefix. But as the ^ is already taken by the
cool RFC 23, my idea have hit a dead end:
-{rwx}
-~rwx
have ambiguity problems.
Hmmm, does
-^{rwx}
have a currying interpretation?
