Spoken languages are inherently vague and open to interpretation and context. As an "engineering type", I would conclude that language is not a good mechanism for communicating concrete details without a lot of scaffolding around it to alleviate the ambiguity. Hence programming, mathematics, diagrams, etc.

On top of that, poems are meant to be "artsy". I.e. They specifically use certain words in odd ways as part of the artistry of it. It's actually a step in the opposite direction of what "engineering types" would want to do to language in order to make it less ambiguous.
