Previous respondents have suggested efficient ways for various circumstances. As for the simplest way:
use Quantum::Superpositions; if ($x == any(@list)) { ... }

Note that the latest release of Q::S (just uploaded to the CPAN last week) is iterator-based and therefore much more efficient that previous versions. We have Steven Lembark to thank for that.

Note too that, whilst the performance of the grep- and hash-based solutions may improve slightly over time, the any solution will continue to improve significantly with future releases of Quantum::Superpositions, then with the new Perl6::Junctions module, and ultimately with the availability of any as a built-in feature of Perl 6.

[Corion]: That will keep the console window open even though the user can't type into it anymore
[thezip]: So I have a script that generates a log file. After script completion, I want tohave VIM open this logfile.
[thezip]: i don't get the command line "back" until I close VIM. No what I want to happen...
[thezip]: I currently don't have access to CYGWIN, else I'd just do a tail -f on the logfile.
[Corion]: thezip: If you want to open vim and can live with opening a second console window, use start "The results" vim.exe c:\path\to\logfile .log
[thezip]: Ooops... I lied. I guess Cygwin is back. I'll just do a tail -f instead. Better. Sorry for the noise.
