[julia-users] How should let this work?

[Miao Yang]

I don't know how to describe my problem, so let me past the code.

```

julia> typealias Foo  (Function, Function)
(Function,Function)

julia> f(foo::Foo) = 1
ERROR: ArgumentError: invalid type for argument foo in method definition 
for f at none:1


```

The Julia version is ` Version 0.4.0-dev+4328 `

And these works recently ...
