I have a bit of SA code where I strip leading and trailing whitespace -

foreach (@addrs) { s/^\s*([^\s]+)\s*$/\1/; }

Whenever I run this I get the warning "\1 better written as $1" which I
understand to be perl telling me that the right side of s/// should use
$digit, not \digit.  I tried changing it to $1, but that didn't produce
the expected result.  What would be the correct way to write this?


s/^\s+//; s/\s+$//;

Your regex doesn't match "  foo bar  " at all.
