Re^3: One regex construct to handle multiple string types

in thread One regex construct to handle multiple string types

It's not about \w, but about backtracking.

\w* initially 'eats' 2L, but then is forced to ... well... put the 'L' back on the table to let \S have it.

Hmm... maybe 'eating' is not the best image for what's going on with backtracking regexps...?

AHHH! Thank you. Enlightenment is mine. "Must-match" versus "may-match" - separating the men from the boys of regex tug-o-war. `for(split(" ","tsuJ rehtonA lreP rekcaH")){print reverse . " "}print "\b.\n";`	[reply] [d/l]
