Method	equiv	Check for logical equivalence. Pass the expression (self <-> other) to the theorem prover. If the prover says it is valid, then the self and other are equal.
Method	make_VariableExpression	Undocumented
Method	negate	If this is a negated expression, remove the negation. Otherwise add a negation.
Method	normalize	Rename auto-generated unique variables
Method	substitute_bindings	No summary
Method	typecheck	Infer and check types. Raise exceptions if necessary.
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	Recursively visit subexpressions. Apply 'function' to each subexpression and pass the result of each function application to the 'combinator' for aggregation:
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...
