Scheme 48 is an implementation of the Scheme programming language as
|
|
described in the Revised^4 Report on the Algorithmic Language Scheme.
|
|
It is based on a compiler and interpreter for a virtual Scheme
|
|
machine. The name derives from our desire to have an implementation
|
|
that is simple and lucid enough that it looks as if it were written in
|
|
just 48 hours. We don't claim to have reached that stage yet; much
|
|
more simplification is necessary.
|
|
|
|
Scheme 48 tries to be faithful to the upcoming Revised^5 Scheme
|
|
Report, providing neither more nor less in the initial user
|
|
environment. (This is not to say that more isn't available in other
|
|
environments; see below.) Support for numbers is weak: bignums are
|
|
slow and floating point is almost nonexistent (see description of
|
|
floatnums, below). DEFINE-SYNTAX, LET-SYNTAX, LETREC-SYNTAX, and
|
|
SYNTAX-RULES are supported, but not the rest of the Revised^4 Scheme
|
|
macro proposal.
