• function-keywords method → keys, allow-other-keys-p

• function-keywords (method standard-method)

• method - a method.
• keys - a list.
• allow-other-keys-p - a generalized boolean.

Returns the keyword parameter specifiers for a method.

Two values are returned: a list of the explicitly named keywords and a generalized boolean that states whether &allow-other-keys had been specified in the method definition.
