Scheme has forms that add bindings to the local scope -- local defines -- but they're similar in spirit to let. There aren't any such functions in standard Scheme, and I don't know of any major implementation that has any. It's not clear how they would interact with macros or macro hygiene, and they would do unpleasant things to lexical scope which is Scheme's original schtick. |
