OK, but in that case we need only add a single sentence: This provides a convenient way to ensure that the arguments to an inlined function are evaluated exactly once, as well as to create local variables. > The misleading part of the existing documentation is that it describes > inline-letevals as similar to 'let' without mentioning that it does a > completely different thing to symbols in the binding list. The only part of your change that I perceive as related to this is the following sentence: When an element of @var{bindings} is just a symbol @var{var}, the result of evaluating @var{var} is re-bound to @var{var}. Is this what caused you to say it "does a completely different thing to symbols in the binding list"? Or did I misunderstand? Thanks.
