 macros which establish bindings.  To be semantically correct, such
 macros must take user declarations into account, as these may affect
 the bindings they establish.  Yet the ANSI standard of Common Lisp does
 not provide any operators to work with declarations in a convenient,
 high-level way.  This library provides such operators.")
