Re: [Haskell-cafe] Failing to catch exception

This was in a draft that got sent by accident. No help needed. I understand why deepseq fixes the problem.

Erik,

Ok, I need some conceptual help on this one. If the action “in" the catch is not evaluated, I would think the catch itself cannot be fully evaluated. Once IO demands the value from the work “in” the catch, how can it escape the catch?

To me it seemed like the exception triggered the death of the wx callback without an evaluation of the catch, like the runtime let it escape.
