Yes and no. With `map`, it depends on the pattern. `>perl -le"@rxs='(.)(.)'; $line = 'ab'; my $cnt = grep $line =~ $_, @rx +s; print $cnt" 1 >perl -le"@rxs='(.)(.)'; $line = 'ab'; my $cnt = map $line =~ $_, @rxs +; print $cnt" 2` [download] `grep` is more robust. It'll work with just about any expression, whereas `map` only works with very specific expressions.	[reply] [d/l] [select]
