[Python-ideas] Re: Delete dictionary entry if key exists using -= operator via __isub__()

I agree that "implicit" does not mean "code that one dislikes." The intent is "delete entry if key exists." Is that implicit or explicit? Positing a default value to discard it as a return value is, arguably, what makes the intent of that construction implicit. I say "arguably," because that is the material that is under consideration (not whether one likes it).
