2010-12-25Simplify let to fn, rather than deal with it through to compilation.David Robillard1-9/+45
The previous implementation of let was a premature optimization intended to make let cheap/free, but screws up closure creation and variable indexing because a new scope is created by something other than fn. Only compile top level expressions to globals (with associated store/retrieve overhead) in a REPL when it is necessary. Add `do' form (ala scheme `begin') to backend (used by `match' simplify). git-svn-id: http://svn.drobilla.net/resp/resp@348 ad02d1e2-f140-0410-9f75-f8b11f17cedd
