Re: Matching @ in string

please always use warnings in perl oneliners. i've never understood why people use warnings in their scripts and leave it out in oneliners.
if i write a oneliner i automatically start it with -wle.
this has probably saved me lots of time.

Possible unintended interpolation of @t in string at -e line 1.
Name "main::t" used only once: possible typo at -e line 1.

I am sure this is very good advice, but in the present case `perl -elw 'if ("h@t" =~ /(\@)/ ) { print $1 }'` doesn't produce any warning (I'm using 5.8.8 under Cygwin and Debian). How did you get the message about the unintended interpolation? loris "It took Loris ten minutes to eat a satsuma . . . twenty minutes to get from one end of his branch to the other . . . and an hour to scratch his bottom. But Slow Loris didn't care. He had a secret . . ." (from "Slow Loris" by Alexis Deacon)	[reply] [d/l] [select]

`perl -elw ...` i said -wle not -elw =) -elw doesn't produce any output.	[reply] [d/l]
