[Python-Dev] dict.merge()?

[Jewett, Jim J]

At the C level, 

	PyDict_Update(old, new) 

is just a shortcut for

	override=1
	PyDict_Merge(old, new, override)

C extensions can use PyDict_Merge directly with override=0, 
which keeps the current value in case of duplicate keys.

Python code can only use update, which means that override
is always true.  Is there a good reason this?
