Gauche predates R7RS, and for the convenience, Gauche makes quite a few procedures as built-in (see Core library). Although the set of Gauche’s core features are mostly superset of R7RS, some functions and syntaxes have different names and/or interface from R7RS.
R7RS fully-compatible syntaxes and functions are available
in the set of modules described in this chapter. Since R7RS
programs and libraries needs to follow a specific format
(import declaration or define-library form),
generally there’s no ambiguity in whether you’re looking at R7RS code
or Gauche-specific code. Also, it is totally transparent to load
R7RS library into Gauche-specific code or vice versa.
However, you need to be aware of which “world” you’re in when
you code.
If you’re familiar with Gauche, take a look at the section R7RS integration, which describes how you can go back and forth between Gauche and R7RS.
