Yes, but that's fine.  A PL language that includes every programming
paradigm would be a total mess, if even possible.  Python has
functional programming where it does not conflict with its overall
design.  The only place I find that this is not the case is with
lambda, but that is now adequately fixed with the addition of the
ternary operator.
