Motivation
Closes #5515 . This problem (
tx.originnot being updated correctly after doingvm.prankafter avm.startPrank) is introduced in part due to #4884 — we now have certain rules to override pranks that weren't explicit enough in the code. You should probably not be able to callvm.prankafter avm.startPrank, asvm.startPrankis "multi-use" and must be stopped, whilevm.prankis "single use", and one should not overlap the other, as you can usevm.startPrankagain after having used the first startPrank. This is made a little confusing as we don't have achangePrankcheatcode, but rather re-usevm.startPrankfor this.We could probably make a case for allowing this, but this feels like a hard-to-explain possible footgun and I'd rather disallow it entirely.
Solution
Disallow calling
vm.prankafter avm.startPrank.
