0.6-rc1 where throwing "invalid type paramer" error in macro

[dlfivefifty]

The following code demonstrates a problem with the new where syntax. Reverting to the old syntax of putting type paramers first fixes the issue:

julia> module FooModule
               macro foo(TYP)
                       quote
                               foofunction(x::Type{T}) where {T<:Number} = x
                       end
               end
               
               struct Foo end
               @foo Foo
       end
ERROR: syntax: invalid type parameter name "FooModule.T"

julia> module FooModule2
               macro foo(TYP)
                       quote
                               foofunction{T<:Number}(x::Type{T}) = x
                       end
               end
               
               struct Foo end
               @foo Foo
       end
