Re: perlfunc index name conflict

If you would like to use supplied Perl index function, qualify it CORE::index.

Also, the second parameter should be a substring to match, not a regular expression. See index.

Good luck. -c

Well, /(\w+)/ will return a substring

[AnomalousMonk]

In scalar context such as supplied by index, a successfully matching regex will return 1, which will be stringized to '1' for the substring for which to search:

>perl -wMstrict -le
"my $str = 'abc1def';
 $_ = 'xyz';
 ;;
 print 'index: ', index $str, /(\w+)/;
 print qq{captured: '$1'};
"
index: 3
captured: 'xyz'

An unsuccessful regex match returns the empty string in scalar context.

Thank you CORE::index has solved my problem.
