A Proposal for Environments in Scheme
Date: Fri, 20 May 88 11:49:26 PDT
Contains exactly those bindings described in the Scheme specification,
except that a given implementation may not provide all of the optional
features. Thus, in this environment, APPEND may or may not accept an
arbitrary number of arguments, LET may or may not allow the named variant,
Except LET isn't a variable.
Can you say:
Presumably not, if the ":" syntax is taken to be an abbreviation for a
call on the ENVIRONMENT-REF procedure.
