Subject: Re: the point of omitting parentheses

One thing, at least with RoR, is if the first param is a hash then 
parens are necessary. e.g.

form_tag({:action=>:update, :id=>1})

I can't remember what error gets thrown if there aren't parens.

Myself, I like not having to type parens. RoR's coding style for patches 
specifies using parens though (which is probably best, to avoid 
ambiguities or errors).

Joe
