(command) if x==list in stata

I want to be able to write an if expression without having to resort to a large number of or "|" operators. For example:

drop if x==1 | x==3 | x==5 | x==7

Is there a simpler way to write this ie:

drop if x==one of (1,3,5,7)

I realize a for loop will work but that isn't a very tidy solution.
