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.

sloppy-memq x lst Deprecated Scheme Procedure
scm_sloppy_memq (x, lst) Deprecated C Function
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.

sloppy-memv x lst Deprecated Scheme Procedure
scm_sloppy_memv (x, lst) Deprecated C Function
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.

sloppy-member x lst Deprecated Scheme Procedure
scm_sloppy_member (x, lst) Deprecated C Function
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.
