library name: records
Many Scheme programmers have considered records to be one of the most important features missing from the R5RS. The R6RS proposed a record system, but its design has been widely criticized and it was not intended for use in R5RS programs anyway.
This SRFI proposes a better record system for use in R5RS, ERR5RS, and R6RS programs. The syntactic layer of this SRFI's record system is an extension of SRFI 9. The procedural and inspection layers of this SRFI's record system are perfectly compatible with its syntactic layer. This entire SRFI is compatible with the procedural and inspection layers of the R6RS record system, but offers several worthwhile improvements over the R6RS system.
