One could disambiguate this the same way it is done with methods:

{ () (a) }

like in

def anonymus() (a) end

or one could use a differnt pair of symbols, though I don't really like that.

{ <a, b=12> a+b }

Though it's easier to type on a german keyboard. (Thats also one of
the reasons I thoroughly dislike any use of the backslash \. Its just
really inkonvenient to me ;)

Brian
