Hopefully this does not stray to close to What's wrong with using grep or map in a void context? but I thought this was an interesting, more readable way to see if a particular (sometimes complex) variable was equal to one of a number of values:

        if( grep { $my->{long}{to}{type}{variable}[0] eq $_ } ( 'val1'
+,'val2','val3' ) )
        {
            #do something...
        }
