A place for talking about the Ethereum Virtual Machine on Farcaster.

Let's say internally you store `var` as a `uint64`, in a public function with a `var` param do you type it as a `uint64` or type it as a `uint256` and `safeCast` it?

Feels like using a `uint256` in the public api is cleaner from a consumer perspective? But obviously at a cost.

Is there a cost? Function arguments are not packed in Solidity, so the param is consuming a u256 anyway, I believe.

`SafeCast` will add some gas at a minimum to run the check, but fairly minimal. Not very clean from an aesthetic standpoint either.
