[Haskell-cafe] Re: what GUI library should i select?

Simon Peyton-Jones wrote in article in gmane.comp.lang.haskell.cafe:

I wonder whether it'd be possible to make the gtk2hs stuff emit warnings if you make calls from two different threads? Then an application would complain constructively rather than "becoming unstable".

... or whether it's possible to represent the gtk2hs thread by a phantom type, to enforce the restriction statically? -- Edit this signature at http://www.digitas.harvard.edu/cgi-bin/ken/sig Batman don't...but Kathmandu!
