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
You can access the type parameters with T.parameters. Have a look at
https://github.com/mbauman/Tuples.jl. Also note possible complications
with vararg types.
However, doing this for non-tuple types this is probably a sign of bad
design as was recently discussed here:
