Pure functions calling weakly pure functions are also weakly pure and so
on. This effectively leaves you without purity.
No. Strong-pure functions can call weak-pure functions and still can be
strong-pure. That's the huge benefit of weak-pure functions -- you can
modularize pure functions without having to change everything to immutable.
