Parsing error with anonymous function

[rborder]

Getting the following error

julia> halfTo = function(k) (1//2)^k end

WARNING: deprecated syntax "k (".
Use "k(" instead.
ERROR: syntax: "^" is not a unary operator

though the following works fine:

julia> plusOne = function(k) 1+k end
(anonymous function)

I know it's inelegant code, but either they should both work or both not work.

On master, the deprecation is now an error, but the problem as such persists. Note that function() () end errors while function(); () end works (anonymous function that returns an empty tuple).

btw, this discrepancy still exists on master. should probably get bug label
