perl6 -e 'my $x="abcsdd1efg1234xyz"; $x ~~ m/(sd..).*(12..)/; say "$0, $1"'
sdd1, 1234
The "?" is to modify the "*" to be "non-greedy" - that is, it will match
the first chunk of stuff that is followed by whatever is after it (so,
"/....*?/" the "?" is certainly unneeded) as opposed to the normal meaning
of "*" which is, "match as much of anything ("excepting newline") as
possible" - so ".*?12" matches up to the first "12" while ".*12" matches as
much as possible up to a last "12"
