Hi All,

�� an attempt to resume an unresumable signal results in raising�IllegalResumeAttempt; quite right:

Exception>>resume

"Return from the message that signaled the receiver."

self resume: self defaultResumeValue

However, IllegalResumeAttempt is not itself resumable. �So in those rare cases (e.g. test coverage) where a knowledgeable client wants to force resumption of a non-resumable signal by catching and resuming IllegalResumeAttempt, they can't because

IllegalResumeAttempt>>isResumable

^ false

So take e.g.

[Cogit chooseCogitClass testPCMappingSelect: [:m| true]]

on: AssertionFailure

do: [:ex| | ctxt |

ctxt := ex signalerContext findContextSuchThat:

[:ctx| ctx sender selector = #allSelect:].

Transcript ensureCr; print: (ctxt tempAt: 1); flush.

[ex resume]

on: IllegalResumeAttempt

do: [:ex| ex resume]]

where I'm trying to JIT every method in my image and catalogue those that assert-fail, proceeding through the assert failure (and AssertionFailure isn't resumable). �I happen to know that proceeding from the assert-fails is safe. �But I can't force resumption because IllegalResumeAttempt is itself not resumable.

I propose that we make�IllegalResumeAttempt resumable. �Objections? �Cautions?

best
