Beware that a CT AA stores its elements in a different order than a

Yes, this is the issue -- the runtime AA depends on druntime, which is
not available to the compiler. The compiler has its own AA
implementation that it uses for CTFE.
The internals will not be the same, which is why you can't construct
one at compile-time and use it at runtime (the enum just recreates it
at runtime when used).

Got it ! Thank you, so I need to write:
enum string[string] CtfeFoo = ["foo" : "bar"];
static immutable string[string] Foo;
static this()
{
Foo = CtfeFoo;
}
string ctfeableFunction()
{
if (__ctfe)
return CtfeFoo["foo"];
else
return Foo["foo"];
}
Ugh, yes, that's required.
Probably can be abstracted in a template.
