Type creep can be a serious concern for dynamic language ecosystems. The Javascript/Typescript schism is a tragic case in point. It appears that young developers are indoctrinated into the belief that strong types are an invincible hammer and can't see the drawbacks that lack of flexibility can introduce. Clojure began with defstruct, and Rich Hickey regrets its addition to the language now. While python certainly is a kitchen sink language, and the addition of structs on top is probably sustainable, but I am of the belief that such suggestions need more counter-arguments lest we lose another mainstream dynamic language to naive good intentions.
