But why would you want to do that? Regexes are one of perl's major strengths, and they can deal with this situation very nicely.

Your code snippet (idx) also seems to be slower than both regex-based solutions given above (zwa, sub): 

       Rate  idx  sub  zwa
idx 73430/s   --  -5% -15%
sub 77672/s   6%   -- -10%
zwa 86374/s  18%  11%   --
