in thread perl -s is evil?

Well, just some fooling around with the last statement Re: Re: Re: perl -s is evil? on my linux box runing Perl 5.005_03, I decided to see what taint checking would do to this example. Wwll here's the results:

$ perl -sleT 'use diagnostics; use strict; "Hello" =~ /(\w+)/; print $ +1' -- -1=foo $
While T in any other position returns
$ perl -sleT 'use diagnostics; use strict; "Hello" =~ /(\w+)/; print $ +1' -- -1=foo foo $

    ummm... You've got a bit of a command like goof there.... The following one-liner illustrates it. Can you figure it out?
    perl -weT 'print "I like jellybeans"' Useless use of a constant in void context at -e line 1.
    consult perlrun for hints. ;-)
