Function-name-listp

Recognize true lists of symbols that name functions.

Signature

(function-name-listp x wrld) → yes/no

Arguments

wrld — Guard (plist-worldp wrld).

Returns

yes/no — Type (booleanp yes/no).

This function is enabled because it is meant as an abbreviation. Theorems triggered by this function should be generally avoided.
