Hello, i've been playing around with std.variant and noticed,
that it does not support elaborate copying, when a struct uses
one. So the question is whether it is intended or not. If yes,
std.variant should probably prohibit usage of such structs. If
no, then it we will need to add a destructor and, and handle
destruction in std.Variant.handler, which will introduce some
performance drop.
Also, i can't completely understand how garbage collection works.
E.g. setting an instance of a class to std.variant will copy its
reference to variant's internal storage, which is void[]. Will GC
loose track of such reference? Thanx.
