I've read in the news that the upcoming Guile 3.0 will unify records. Core records type seem to support the procedure "record-accessor", which takes a field name as a symbol.
In R7RS (based on SRFI 9), record field names are, however, (hygienic) identifiers and thus compile-time and not run-time identities. An R7RS record type can, therefore, not support "record-accessor" and similar procedures. How is this going to be solved in Guile 3? See the Rationale of SRFI 150 why R7RS record types use hygienic identifiers (and should do so) for field names. Marc
