What is the type of this C# expression? (f, a, b) => from aa in a from bb in b select f(aa, bb)

@dibblego I'm going to guess it did not infer Func<Func<a,b,c>, IEnumerable<a>, IEnumerable<b>, IEnumerable<c>>

@sgoguen Why should IEnumerable even come into it?

@dibblego AFAIK C# doesn't support types that generically covers both default implementations: IEnumerable and IQueryable. Am I close?

@sgoguen @dibblego csc can't infer type of a lambda. Theoretically Func<Func<a,b,c>,M<a>,M<b>,M<c>> where M supports SelectMany aka bind?

@kurt2001 @dibblego Thanks. I've been spending so much time with F#, I forgot this doesn't work. http://share.linqpad.net/lhl2tu.linq  :)
