I see that you used a constructor to initialize everything. Won't that
be enough to know that tlv_get_addr is correctly initialized? No D code
will be able to run before that, as far as I understand.
On OS X tlv_initializer will be called by _dyld_initializer which is
called by libSystem, if I understand the source code of dyld correctly.
This doesn't happen on iOS?
