Macros with for loop arguments are parsed differently in comprehensions

[simonster]

These work:

[for i = 1:10 end for i = 1:10]
@inbounds for i = 1:10 end
[@inbounds(for i = 1:10 end) for i = 1:10]
[@inbounds begin 
    for i = 1:10 end
end for i = 1:10]

These do not:

[@inbounds for i = 1:10 end for i = 1:10]
[begin
   @inbounds for i = 1:10 end
end for i = 1:10]

The extra parens seem advisable there.

I agree that [@inbounds for i = 1:10 end for i = 1:10] is not so clear, but code in a begin/end block inside a comprehension seems like it should have the same rules as code in a begin/end block outside of a comprehension.
