Makes most of the bindings documented in this module available. See Overview for information on why this declaration is required.

Like provide, but ids under unsafe are not actually provided. Instead, they are collected for introduction into an importing module via a macro created by define-unsafer.

Cooperates with provide* to define id as a unsafe!-like form that introduces definitions for each binding provided as unsafe. The define-unsafer form must occur after all the provide* forms to which it refers.
