Invalid Keyword Arguments (original) (raw)

ANSI Common Lisp 3 Evaluation and Compilation 3.5 Error Checking in Function Calls 3.5.1 Argument Mismatch Detection

3.5.1.5 Invalid Keyword Arguments

It is not permitted to supply a keyword argument to a _function_using a name that is not a symbol.

If this situation occurs in a safe call, an error of type program-error must be signaled unless keyword argument checking is suppressed as described in Section 3.4.1.4.1 Suppressing Keyword Argument Checking; and in an unsafe call the situation has undefined consequences.
