I'm not a huge fan of augmenting uint256 like this. It makes the source of this less clear. It feels a touch too clever.

Same thing as with randomness, IM,O there is no harm in it being FVMPay.burn(amount) and it makes the code much more readable.

I made this library to reuse the precompile code and its mocks across repositories, after demonstrating that the precompile native send method uses less gas.
