It occurred to me that there is a workaround which deals not only with the
void case, but also with the case where the types of e2 and e3 are different
(and the result is to be ignored): "e1?(e2,0):(e3,0)".  I'm not sure whether
to recommend this in cases where an expression is required instead of a
statement, or to draw back in horror.

This case is not covered by my suggestion.  I find it hard to imagine doing
it, however.
