It's a well-known limitation. The workaround is:
immutable long[string] aa;
static this() {
aa = [
"foo" : 5,
...
];
}
All right! No language has to be perfect... (I'm joking). But the doc (the
language ref for the matter) should definitely say what you just explained
above, shouldn't they? I actually think clearly stating limitations is a +++.
(Like an industry company that does not make perfect product but has great
client support.)
