- Support for Python namespaces:
If you have a Python module foo, in order to use its contained objects in LLDB you do not need to use 'from foo import *'. You can use 'import foo', and then refer to items in foo as 'foo.bar', and LLDB will know how to resolve bar as a member of foo. Accordingly, GNU libstdc++ formatters have been moved from the global namespace to gnu_libstdcpp and a few test cases are also updated to reflect the new convention. Python docs suggest using a plain 'import' en lieu of 'from-import'. llvm-svn: 138244
