Context.get() is inherited from Mapping.get(); if you want it to raise use Context.__getitem__() (i.e. ctx[var]). Lots of classes define get() methods with various behaviors. Context.get() and ContextVar.get() are just different -- ContextVar is not a Mapping. -- --Guido van Rossum (python.org/~guido)
