in thread How to avoid $_ in grep

Great advice, and might I add:

use English qw( -no_match_vars );

is an even better idea.

perl -e 'split//,q{john hurl, pest caretaker}and(map{print @_[$_]}(joi
+n(q{},map{sprintf(qq{%010u},$_)}(2**2*307*4993,5*101*641*5261,7*59*79
+*36997,13*17*71*45131,3**2*67*89*167*181))=~/\d{2}/g));'

Ah, I didn't know this... those match variables are more trouble than they're worth! Thanks for the tip!	[reply]
