It would seem to me that $& would be more readable than substr( $str, $-[0], $+[0] - $-[0] ). 

use strict;

while(<DATA>)
{
  chomp;
  /\d+$/;
  print "Numeric: [$&]\n";
}

Is there a case where you would use the substr over $&?

"Look, Shiny Things!" is not a better business strategy than compatibility and reuse.
