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

Yes, but the man page doesn't say that it's a variable: it says that 
the <i>property</i> thing in the "set" statement is the name of a 
property. The name. Not "a variable evaluating to a name". And I 
think that needs to be pointed out explicitly, because the obvious 
possibilities are 1/ only the actual name is allowed 2/ any 
expression giving a name. I don't understand at all why here only a 
name or a variable is allowed.
