I don't think so.
It would probably result in $0 containing an array of match objects,
one for each possible match. Each of those second tier match
objects would then have a 'match' key in its hash attribute.
Hence, to see the individual hypotheticals one might write:
for @$0 -> $possible_match {
print $possible_match{match}, "\n";
}
A more intriguing possibility is that the top-level match object ($0 itself)
would *also* have a 'match' key...whose value contained a superposition of all
the possible hypotheticals. So you could also just write:
print egs( $0{match} _ "\n" );
Bwah-ha-ha-ha-hah!!!!!!
