Use of such features in PreScheme programs is +restricted to those cases that can be compiled into efficient code. + +Type reconstruction is done using a modified Hindley/Milner algorithm +that allows overloaded user-defined functions. + +All top-level forms in PreScheme programs are evaluated at compile +time, which gives the user additional control over the compiler's +partial evaluation of a program. + +PreScheme has been implemented and used to write a byte-code +interpeter and associated support code for a complete Scheme +implementation. + +## Manuals + +* [The Nearly Complete Scheme48 PreScheme 1.3 Reference Manual](1.3/) + +## Implementations + +### Scheme 48 + +### VLISP + +No known public release. + +### SPS + +SPS is a Pre-Scheme to (GNU) C compiler written in Pre-Scheme. + +Written in 1999. + +[GitHub](https://github.com/nineties-retro/sps) + +## Research papers + +From the MITRE Corporation: + +* A Verified Compiler for Pure PreScheme (1991) +* The VLISP PreScheme Front End (1992) +* A Verified Run-Time Structure for Pure PreScheme (1992) +* The Revised VLISP PreScheme Front End (1993) +* The VLISP Verified PreScheme Compiler (1995) +* A Verified Compiler for Multithreaded PreScheme (1996) + +From Kelsey: + +* Pre-Scheme: A Scheme Dialect for Systems Programming (1997)
