August 31, 2016

Quick pLisp update: pLisp is now much more liberal with respect to symbol names: almost any character is acceptable, except for ten or so 'special' ones like backquote, comma, double quotes, and so on. This has resulted in the added benefit of doing away with things like LET1 and CALL-CC and going with the more standard LET* and CALL/CC.  Also, built-in functions like + and CAR can now be used wherever user-defined functions can be used, e. g., as arguments to APPLY and FUNCALL. This was achieved by creating user-defined wrapper functions for the built-ins; profiling indicates that there isn't much of a performance hit because of this additional indirection.
