Sample precompile in Rust: https://github.com/ewasm/ewasm-precompile-sha256/blob/master/src/lib.rs

Proposal to expose these functions from the EEI: - `useGas` - `getCallDataSize` - `callDataCopy` - `getCaller` (good for contracts like blockhash - or should be `getTxOrigin`?!) - `getCallValue` (not necessary,...

We had used `consumeGas` in other places. For example: https://github.com/ewasm/ewasm-rust-api/blob/master/src/lib.rs#L115

@aj07 are you interested in adding an FAQ entry for this?

@chriseth since you mentioned the requirement for this, can you please explain why we should have it?

I would argue this is not needed, because wasm cannot be introduced without the client knowing about it, and if it does, it can easily detect the "wasm magic" as...

The check is useful for two reasons: 1. Better error reporting 2. Saving gas in the failure case (i.e. when this signature check is preceding an EIP-1271 verification -- this...
