We might also want an option to toggle a weak/non-weak flag, like we have for references

I was going to ask if we could use node::Persistent instead, but then I realized that was an internal API. LGTM.

Regrettably that's not going to fix the memory leak in already compiled add-ons since it's an inline definition. Can I suggest moving the method bodies to a .cc file?

edit: to be clear, that won't fix the add-on issue right away either but it helps avoid such issues in the future.

@bnoordhuis it should fix it for N-API addons since the inline should be behind the N-API c functions so I'd like to get it landed and do the refactoring as a follow on.
