Tried a code snippet with Gambit 4.7.4 on my iPhone and got an unbound variable error for filter. I noticed the same thing on my laptop’s version (4.8.9). Dybvig’s 4th edition of The Scheme Programming Language lists filter as part of the language on page 164.
Why does it not exist in Gambit Scheme?
