8 Macros for Unsafety

(unsafe!)

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

(provide* provide-star-spec ...)

provide-star-spec   =   (unsafe id)     |   (unsafe (rename-out [id external-id]))     |   provide-spec

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.

Providing users with unsafe operations without using this facility should be considered a bug in your code.

(define-unsafer id)

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.
