you can have two kind of if-bind, the one in arnesi and the one that covers
most of the use-cases is a single var version:

(if-bind var expression
  then
  else)

but one can have an:

(if-let ((var1 expr1)
          (var2 expr2))
  then
  else)

which should expand to nested let's with an if's to keep the semantics of
'and.

but imho this if-let idiom is not needed that often to justify the extra
syntax for the single var case and the extra semantic complexity
(non-obviousness).
