Macro hygiene problem with closures

[toivoh]

With the latest julia, the following code

module Lib
export @make_closure
macro make_closure()
    quote       
        f = (x)->1
    end
end
end # module

module Test
using Lib
@make_closure
end # module

gives me

ERROR: syntax: malformed function arguments (. #<julia: Lib> 'x)
 in include at boot.jl:238
at /home/toivo/code/julia/juliastuff/issues/closure-hygiene/test.jl:15

With julia Commit ba9d7e5* 2013-10-15 15:00:57 UTC it works fine. It seems that macro hygienization believes that the argument x in (x)->1 is a global variable. This also seems to be the cause of toivoh/PatternDispatch.jl#17.

@JeffBezanson Does this hold back 0.2?

This is also seems like something we should have a test for.
