I prefer pure Lua libraries too, when possible, for two reasons.

The first one is portability to sandboxed environments, or to environments where the C compiler is very
limited, or to environments where hot code reloading is necessary...

The second one is for teaching / human accessibility purpose. I want some developers who do not know C
code to be able to read and understand the source code of the libraries.

Finally, pure Lua libraries can be faster with LuaJIT sometimes. I don't really care about that
since I use 5.3 myself though.

The best solution is probably to have modules which support both: a pure Lua implementation and a compatible,
faster C implementation with the same API, which can be used if available. That's what I did with my
lua-chacha module, for instance:

I actually have a semi-stealth project to write a collection of pure Lua 5.3 libraries for network protocols,
file formats and modern cryptographic schemes. I do not intend to include YAML in it for now, though.
