If this is a feature, it's a nasty one.

Well no, that was just a toy example.

So I'm finding out.

But it's weird: according to the man page the "something" of 
something can only be given as a keyword, it's not an expression that 
is evaluated to give that keyword (wouldn't it be cool if that was 
the case?), so why is expansion/substitution being applied to it? 
(I'm spoiled: I'm used to TeX where expansion mechanisms are 
abstruse, but extremely logical.)
