Since EVM uses 256-bit integer arithmetic, most operations on such variables just work. The only situation which requires special attention is iteration against absolute slot addresses: the invariant that the last slot belonging to a variable has the highest address does not hold. When implemented incorrectly, a loop over an array will immediately terminate if the container spans the end of storage - due to the initial position already being greater than the end position. This affected storage array clearing loops generated by both evmasm and IR pipelines. Additionally, (only in the evmasm pipeline) c
