Cannot interpolate a function into a method declaration.

It's possible to embed a function (not a symbol that represents the function) in an expression and execute it. It seems like it should also be possible to embed a function in an expression and define a new method for it.

julia> f() = 1
f (generic function with 1 method)

julia> eval(:($f()))
1

julia> eval(:(f() = 2))
f (generic function with 1 method)

julia> f()
2

julia> eval(:($f() = 3))
ERROR: syntax: invalid function name "Main.f" # Actual
f (generic function with 1 method)            # Desired

julia> f()
2 # Actual
3 # Desired

That's not something we really support since the frontend will never emit such expressions. Resolved bindings like this will be represented as GlobalRefs instead.

Thanks. GlobalRef was what I was looking for.
