WithCleanup

WithCleanup[expr,cleanup] evaluates expr, running cleanup before returning the result, even if an abort, throw, etc. was generated during the evaluation of expr.

WithCleanup[init,expr,cleanup] evaluates init before evaluating expr, blocking aborts, throws, etc. in both init and cleanup.

Examples

Ensure cleanup runs even after an abort:

WithCleanup[Print["Working..."], Print["Cleanup!"]]
(* Working... *)
(* Cleanup! *)
