"""
Utility method to parse a (unicode) string of code. This is mostly
used for internal Cython compiler purposes (creating code snippets
that transforms should emit, as well as unit testing).
code - a unicode string containing Cython (module-level) code
name - a descriptive name for the code source (to use in error messages etc.)
RETURNS
The tree, i.e. a ModuleNode. The ModuleNode's scope attribute is
set to the scope used when parsing.
