What is the simplest way to extract a matched subexpression?
Eg. in perl you can do
"hello world" =~ m/hello (.*)/
which would return 1(true) and set $1 to the matched subexpression
"world".
If you wanted a logical value returned, then
?grep
If you want the matched subexpression, use , value=TRUE.
??"regular expressions"
