@ethers Thanks JC, very good find. When it comes to compiling `library`, solc places placeholder like `__:BasicMathLib_________________________` in the output, and one has to insert address of those library placeholder...

As we discuss before, we want to make our `trait MerkleTree` and our implementation generic beyond just ``, I have some ideas, we should discuss and pair-program on this change....

I see, I was so entrenched in seeing and using function signature like `&mut R`, now I actually kind of like the current API design. Feel free to close this...

another tangential question, why are we marking `rng: RngCore + CryptoRng` instead of `rng: Rng + CryptoRng` in user-facing APIs? @tarcieri didn't [`rng_core`'s doc](https://docs.rs/rand/latest/rand/trait.RngCore.html) suggests that only Rng implementations should...

@corysimmons Thanks for the answer, I'm using Ubuntu18.04, `Ctrl-Space` collide with my keyboard switch shortcut. Any suggestion or how can I change `graphiql`'s default?

Upvote for releasing a fast latex & bibtex formatter as a separate executable. (Ideally I'd like to configure my emacs/lsp to use this formatter by default, and use pre-commit hooks...

thanks for the suggestion @clason, I'm quite a noob when it comes to Tex tooling, may I ask what's the benefit of an independent formatter in latex-lsp over hooking up...

Done @rozbb (btw, didn't remove the unused methods `ExpandedSecretKey::from/to_bytes()`)
