36.2 `Sloppy' List Membership Procedures

The following are equivalent to memq, memv and member respectively, except that they do not fully type-check the arguments that they are given. They are deprecated because the lack of proper type-checking makes them dangerous.

Deprecated Scheme Procedure: sloppy-memq x lst
Deprecated C Function: scm_sloppy_memq (x, lst)
This procedure behaves like memq, but does no type or error checking. Its use is recommended only in writing Guile internals, not for high-level Scheme programs.

Deprecated Scheme Procedure: sloppy-memv x lst
Deprecated C Function: scm_sloppy_memv (x, lst)
This procedure behaves like memv, but does no type or error checking. Its use is recommended only in writing Guile internals, not for high-level Scheme programs.

Deprecated Scheme Procedure: sloppy-member x lst
Deprecated C Function: scm_sloppy_member (x, lst)
This procedure behaves like member, but does no type or error checking. Its use is recommended only in writing Guile internals, not for high-level Scheme programs.
