Oops, except you have the arguments tranposed (thanks to shaver for pointing this out to me).
import extend from "@obj";
Any mutating function should take uncurried "this" as first parameter. Separate argument: strcpy/memcpy/memmove from Unix libc all imitate assignment by copying right to left. Anything else is a sanity challenge (I've had to deal with gdb vs. Intel x86, which disagree on this [gdb is wrong] for way too long).
