However, though not part of R7RS-small, SRFI 69 hash tables are fairly pervasive, because they are simple, have a reference implementation, and can be built on top of R6RS hashtables (which are standard). The only reason they aren't in more Schemes is that as SRFIs go, 69 is a fairly recent one. I wouldn't hesitate to use them. -- "But I am the real Strider, fortunately," John Cowan he said, looking down at them with his face cowan@xxxxxxxx softened by a sudden smile.
