Your point is absolutely correct, but I think your example is a little unfair. There are a ton of template libraries that handle inheritance or code sharing in both Python and Java, some restricted to XML, others freeform. Saying that any one on either side has "solved" it ignores the others that have approached the problem from another direction.

For my money, a better example is the comparison between http://www.oracle.com/technetwork/java/index-jsp-135475.html and http://www.python.org/dev/peps/pep-0333/. Or http://rack.rubyforge.org/doc/SPEC.html, for that matter.
