if (grep {$foo eq $_} @fooarray) {be there light}
The grep{} loops over a list/array, evaluates the condition for each
element and returns a list of elements that were accepted or (in
scalar context) the number of times the condition was true.
If you do this a lot you should consider using a hash. Then you could
write the condition like this:
if (exists $foohash{$foo}) {be there light}
Consult your books about hashes.
