lgtm, nice to simplify!

There's a deadlock with re-entering the global shell here, looking into it

Happens here:

Lines 779 to 783 in 91cfab4

	if let Some(gas_report) = gas_report {
	let finalized = gas_report.finalize();
	sh_println!("{}", &finalized)?;
	outcome.gas_report = Some(finalized);
	}
