Dear cafe,
does anyone have an explanation for this?:
error (error "foo") *** Exception: foo
error $ error "foo" *** Exception: *** Exception: foo
I don't know if this is relevant, but I thought that the GHC compiler believes that all exceptions are equivalent and indistinguishable - that is, in the presence of multiple exceptional code-paths it will make optimizations that would not otherwise otherwise be sound. That might not be the issue here, but it is interesting. http://research.microsoft.com/en-us/um/people/simonpj/papers/imprecise-exn.h... Antoine
