Then I change the "Test.setIt" method as follows:

Error on "s = cast..." line:
cannot cast module socket of type void to shared(Socket)
Apparently std.stdio defines an alias `sock` to some module.
When
you import std.stdio, its `sock` takes precedence over the
parameter `sock`.
It's been discussed recently, but I can't find it now. It's a
natural result of the scope hierarchy: parameters are in a higher
scope than the function body, into which the identifiers from
std.stdio get imported.
It's been recognized that this is often unexpected, and different
lookup rules have been debated, but I think there was no clear
conclusion.
But in this particular case, it has already been fixed, and will
work in the next release:
