Subject: Re: The finer points of postfix conditionals.

Thanks for the explanation. FWIW I think it is a shame that postfix 
conditionals are semantically different to normal ones, but it's good to 
know why the difference occurs.

I started to wonder about this when I was using the following code:

bla(foo) if foo = self.foo

In other words, I was trying to put the value of the method foo into the 
local variable foo in order to avoid calling the method twice. To me the 
above is quite an elegant way of doing that, so it's a shame that it 
does not actually have the intended effect ;) [it all came crashing down 
when I renamed the foo variable]

Cheers
