A Record Type Representation Trick
I’ve been working on optimizations in Loko Scheme recently and have implemented large parts of A Sufficiently Smart Compiler for Procedural Records (Keep & Dybvig, 2012). At the same time I have improved the representation of record type descriptors and wanted to share a simple trick I used to improve record type checks for non-sealed records. But first I should explain what a record is in Scheme.

Today we have two major leaders in file system semantics: Windows and POSIX. They are very close to each other when compared to the full set of possibilities. Interesting things happened before POSIX monopolized file system semantics.
