This submodule contains some functions which cannot be typed or some functions
for which Typed Racket cannot produce contracts, i.e. polymorphic functions of
variable arity. The definitions in this submodule specifically target untyped
user code.
Since the names of some of the definitions in this submodule are the same in
the main module, and since they are imported in the same namespace for
rendering this document, some references to untyped definitions may wrongfully
point to typed definitions. As a tentative fix, all such references are
accompanied by the explicit mention "untyped".
