<div dir="ltr">If there is a set(PARENT_SCOPE) why isn't there an unset(PARENT_SCOPE)? It seems like a hole in the API.<div><br></div><div>I noticed this when I was trying to update my push_variable/pop_variable functions. I use set(PARENT_SCOPE) to set the variable outside of the function, but when doing pop_variable I want to use unset(PARENT_SCOPE) if the variable was undefined before push_variable.</div>
