in reply to How to check if a variable's value is equal to a member of a list of values
could you please elaborate more, I don't really understand your usage of values and keys.
lookups of strings (!) are most efficient with hashes, ...
> then just using something like 1 for the value.
... and you don't need to assign any value, undef is enough
my %look; @look{@set_of_values}=(); ... print "gotcha" if exists $look{$to_check};
You're free to put anything other than undef in the slots if you need to do further checks.
Someone proposed using smartmatch ~~, but I doubt this scales well in repeated use (if their is no magic background optimization happening)
