Well, thanks everyone, I think I understand now why it doesn't work when
specifying Array{Any}, and your answers completed each other.
What I still fail to understand is why how Julia manages to choose the
correct function, assume I still have:
function f(s)
println(s.x)
end
function f{T}(sl::Array{T})
for s in sl
f(s)
end
end
If I call f on an Array of state, how does Julia know that it has to choose
the second function... After all, the argument of the first function could
still be an Array of state...
