This seems nicer:

(if CONDITION
    do-this-if-CONDITION-then-exit...
    (let ((x foobar) y z (foo 5) a)
      ...))

Are there other macros where bindings continue in effect cond* style?

It looks like everybody is trying to design a "do it all super-macro"
instead of using something like cl-destructuring-bind.

That looks like writing (let (`(,foo 42)) ...)

Are there other macros where unquote marks variable name?
