[ MarshalError ] But SimonM said that he doesn't want to make errno Haskell thread local...

Wasn't this only due to efficiency reasons? IIRC Fergus had a good suggestion (copying errno only on thread switches or something), so I'd like to hear Mr. HsLibs' opinion on this topic again.

It'll have to be done (copying errno on thread switches, that is). But I still hate it.

...

[ MarshalUtils ] BTW, can't we just use `with' now. IIRC, the only reason Marcin used `withObject' was because of a clash with the implicit parameter extension. This has been changed now, hasn't it?

Nope, not yet. Although there was some consensus about SPJ's ?-suggestion for those bindings, it's not implemented yet. Any takers? If this has been done, `with' would be better, indeed.

Agreed.

...

And just a final topic which really should be settled: "Marshal" or "Marshall"?? :-}

I would have taken the latter, but I think, SimonM originally proposed the name MarshalUtils with one "l" and as he is the native speaker...

dictionary.com recons that 'Marshal' is the correct spelling. 'Marshall' is a military rank only, AFAICT. Cheers, Simon
