[Python-checkins] python/dist/src/Lib/test test_copy.py,1.4,1.5

[gvanrossum@users.sourceforge.net]

Update of /cvsroot/python/python/dist/src/Lib/test
In directory sc8-pr-cvs1:/tmp/cvs-serv11280/test

Modified Files:
	test_copy.py 
Log Message:
Add support for copy_reg.dispatch_table.

Rewrote copy() and deepcopy() without avoidable try/except statements;
getattr(x, name, None) or dict.get() are much faster than try/except.
