Thanks jakeease and Anonymous for the feedback so far! I just thought I'd clarify: Yes, it's a bit like an enum - the thing is though that I'd like to retrofit some older scripts that already use a scalar as an enum. It'd be an advantage if I could just add a line at the top saying "restrict this scalar to this set of allowed values" to protect against future typos instead of updating every place where the scalar is used.
