Auxillary functions
cleanExpr :: Expr -> Expr Source #
Remove all custom symbols from the expression
Useful/necessary for comandisons.
Note that it is not possible to remove all symbols (and,or,magicNat,magicVar)
underSubst :: (Expr -> (Expr, [Attribute])) -> Expr -> Maybe (Expr, [Attribute]) Source #
Substitutes all special vars with a unique regular Var then applies some function after which the substitution is reversed
