#

Function SPECIAL-OPERATOR-P

Syntax:

special-operator-p symbol => generalized-boolean

Arguments and Values:

symbol---a symbol.

generalized-boolean---a generalized boolean.

Description:

Returns true if symbol is a special operator; otherwise, returns false.

Examples:

     (special-operator-p 'if) =>  true
     (special-operator-p 'car) =>  false
     (special-operator-p 'one) =>  false

Side Effects: None.

Affected By: None.

Notes:

Historically, this function was called `special-form-p`. The name was finally declared a misnomer and changed, since it returned true for special operators, not special forms.

The following X3J13 cleanup issue, not part of the specification, applies to this section:
