During our work on the Gas Station Network we have encountered a problem with the way such concepts as gas limit and gas refund are somewhat hidden from smart contracts. With the current EVM, the core GSN smart contract (RelayHub) is not able to precisely track the gas usage by a transaction due to these limitations.
Exposing such parameters as transaction gas limit, current execution frame gas limit, and current refund counter is an extremely simple and useful improvement to the EVM.
