defun-proto

Arguments: name varlist &body body

This macro is very similar to defun, except that only declarations are noticed from the first part of the body; the rest of the body is ignored (and the operator is not actually defined -- defun must also be called). This macro allows the programmer to declare dynamic arguments for a function before its first use, which might come before the actual definition. If the prototype and the actual definition give different specifications, then it is treated just like a redefinition, and warnings are given subject to with-compilation-unit behavior.
