I think the underlying reason why it does not work is that
dynamic array manifest constants are messed up. I.e. class
reference `enum`s are disallowed in order to avoid having to
make a decision for either inconsistent or insane semantics.
Well from my point of view enum is just evaluate this
expression at the usage site. So any array or class instance
will be created anew at the point of usage.
What are the problems with enums and dynamic arrays?
I think Timon is referring to:
enum int[] foo = [1,2,3];
auto bar = foo;
auto baz = foo;
assert(!(bar is baz)); // Passes
