I wonder if we should mark if-let and when-let obsolete instead.
Because it is only a special case of the if-let* and when-let* forms
(with only one binding), so it is absolutely redundant.  Also, I find
the new syntax breaking with the binding-list syntax of let confusing.
Finally, it would ease the transition for programmers: the modified
if-let and when-let break existing code, and it's not obviously for
programmers what's suddenly wrong.


Michael.
