; syntax: assert ?expr ?expr ... [report: ?r-exp ?r-exp ...]
;
; If (and ?expr ?expr ...) evaluates to anything but #f, the result
; is the value of that expression.
; If (and ?expr ?expr ...) evaluates to #f, an error is reported.
; The error message will show the failed expressions, as well
; as the values of selected variables (or expressions, in general).
; The user may explicitly specify the expressions whose
; values are to be printed upon assertion failure -- as ?r-exp that
; follow the identifier 'report:'
; Typically, ?r-exp is either a variable or a string constant.
; If the user specified no ?r-exp, the values of variables that are
; referenced in ?expr will be printed upon the assertion failure.
