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.
