Hi Monks, I'm new to Perl and trying to figure out how to only replace matches after the initial match using regex. For example, I would like to replace any matches of bar with foo after finding the first bar.

Input foofoo
Output foobar

I have tried what I believe is look ahead assertion 

$s = s/bar(?=bar)/foo/;

However it seems to get rid of everything and print an empty string.
