Sure its useful. Over at id:249381 I had to create a short function indexany() for use in the grep. If @searchCriteria were actually a disjunction then this code doesn't require the new function anymore.

# Without disjunctions
sub indexany { -1 != index $_, $_[0] and return 1 for @_[1 .. $#_]; re
+turn 0 }
@newArray = grep indexany($_, @searchCriteria), @largeArray

# With disjunctions
$searchCriteria = any( @searchCriteria);
@newArray = grep -1 != index($_, $searchCriteria), @largeArray;

That depends on what you mean ;-)
