I hate that idiom in English, too.  If you're going to give me a forking
conditional, I want to know about it early.

Basically, I can handle
	do x if y
pretty well, but
	do x if y else z
always breaks my parser.

So in English, I might say "I'll go to the store if I have time", but
I'd rarely use "I'll go to the store if I have time, otherwise I'll send
the house elf"; instead, I'd say "If I have time, I'll go to the store,
otherwise I'll send the house elf."
