[julia-users] Check if type "contains" Any

[Tommy Hofmann]

I would like to write a function "contains_any(T)" which checks wether a 
type T "contains" Any. For example

contains_any(Integer) = false
contains_any(Any) = true
contains_any(Tuple{Integer, Any}) = true
contains_any(Tuple{Tuple{Integer, Any}, Float64}) = true

etc. How could one do this in julia?

Thanks,
Tommy
