Hello, Is an environment implemented as plain Scheme data? If yes, is the current environment (I mean the set of currently "lookup-able" symbols) accessible? Hope I'm clear (don't know yet Scheme's proper vocabulary yet). I'm thinking at something along the lines of: (getSymbolValue env 'a) beeing equivalent, for a symbol 'a, to: (eval 'a) and (defSymbol env 'a 1) equivalent to: (define a 1) Aside pure reflexivity, this would allow some nice tricks, like unpaking an associative table into the current env: (unpack (parseRecord line)) where parseRecord returns eg a (name phone email) table, would def symbols under those names in env.
