You find our discussion here:

http://www.open-std.org/jtc1/sc22/wg14/www/docs/n2239.pdf

I don't think that there has been a follow-up after that.

I think the misunderstanding in N2207 (also when discussing the
ternary operator later on) is that the expression in an `assert`
should be be considered after all implicit conversions, and the text is
indeed not clear about that.

A minimal clarification of all of that could be achieved by replacing
the "have a scalar type" to "evaluate to a scalar type". If we'd want
something in the direction of Martin's text, I would more go to "which
shall be implicitly converted to _Bool", and then strike-out the whole
explanatory ("that is ...") subphrase.
