A.1 Base Library ¶

The (scheme base) library exports many of the procedures and syntax bindings that are traditionally associated with Scheme. The division between the base library and the other standard libraries is based on use, not on construction. In particular, some facilities that are typically implemented as primitives by a compiler or the run-time system rather than in terms of other standard procedures or syntax are not part of the base library, but are defined in separate libraries. By the same token, some exports of the base library are implementable in terms of other exports. They are redundant in the strict sense of the word, but they capture common patterns of usage, and are therefore provided as convenient abbreviations.
