Property	args	Return uncurried arg-list
Property	pred	Return uncurried base-function. If this is an atom, then the result will be a variable expression. Otherwise, it will be a lambda expression.

Method	free	Return a set of all the free (non-bound) variables. This includes both individual and predicate variables, but not constants. :return: set of Variable objects
Method	negate	If this is a negated expression, remove the negation. Otherwise add a negation.
Method	normalize	Rename auto-generated unique variables
Method	replace	Replace every instance of 'variable' with 'expression' :param variable: Variable The variable to replace :param expression: Expression The expression with which to replace it :param replace_bound: bool Should bound variables be replaced...
Method	substitute_bindings	No summary
Method	variables	Return a set of all the variables for binding substitution. The variables returned include all free (non-bound) individual variables and any variable starting with '?' or '@'. :return: set of Variable objects...
Method	visit_structured	Recursively visit subexpressions. Apply 'function' to each subexpression and pass the result of each function application to the 'combinator' for aggregation. The combinator must have the same signature as the constructor...
