The concept of modality aims at solving this problem.

Modality is just a set of constraints bound to a particular
proposition (function). They can decide whether to transfer the
execution to the main proposition or reject it [1]. Moreover, they can
not only restrict but also add some tiny layer of behaviour, thus
alleviating the need for decorators (OOP) or monads (FP). You can see
from the link that they do it in a more natural way, without type
acrobatics, which means that in future, we can train Logos to
comprehend natural languages with more ease.
