[issue8419] dict constructor allows invalid identifiers in **kwargs

[Raymond Hettinger]

Raymond Hettinger <rhettinger at users.sourceforge.net> added the comment:

Does this mean that every time someone uses **kwds, that the entire dictionary will need to be scanned for invalid keys?  So every API that accepts and passes through **kwds will be slowed on every time it is called.  Is there any offsetting benefit?
