The "conflating" form of `lambda/kw' is furthermore dangerous when used in macros: Assume `(lambda/kw (x y (z)) ... w ...)' is in the template of a macro where `z' and `w' are macro parameters.

Can you spell this out in detail with an example?  I have a fairly concrete mind (which is not to say that it is actually made of concrete).
