Subject perl experts - \1 better written as $1 ?
Date Thu, 10 Jun 2010 06:36:35 GMT
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?
