It is intended to +allow a bit more compile-time introspection of environments in Common Lisp. + +Quite a bit of information is available at the time a macro or compiler-macro +runs; inlining info, type declarations, that sort of thing. This information +is all standard - any Common Lisp program can @code{(declare (integer x))} and +such. + +This info ought to be accessible through the standard @code{&environment} +parameters, but it is not. Several implementations keep the information for +their own purposes but do not make it available to user programs, because +there is no standard mechanism to do so. + +This library uses implementation-specific hooks to make information available +to users. This is currently supported on SBCL, CCL, and CMUCL. Other +implementations have implementations of the functions that do as much as they +can and/or provide reasonable defaults.") + (license license:wtfpl2)))) |
