Yep, enum is a compile-time thing.

This code doesn't compile:
class A {
this(uint i) {}
}
enum myEnum : A {
entry1 = new A(0),
entry2 = new A(1)
}
void
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 mean construction via field-by-field assignment. (I made the same
typo in the bug report, lol).
