*I mean construction via field-by-field assignment. (I made the same
typo in the bug report, lol).
There's also this bug where the constructor for a struct isn't called:
http://d.puremagic.com/issues/show_bug.cgi?id=5460 , and field
assignment is not disabled even with the presence of a constructor.

I don't think so. Enums are compile-time constants.
This code doesn't compile:
class A {
this(uint i) {}
}
enum myEnum : A {
entry1 = new A(0),
entry2 = new A(1)
}
void

... or does enumerations only support constant-expressions? Thanks!
Yep, enum is a compile-time thing.

Hey guys,
is it possible to declare a enum where all entries are instances of a
class (or struct), like the following:
class a {
...
public this(uint i) {
...
}
...
}
enum myEnum : a {
entry1 = new a(0);
entry2 = new a(1);
}
