New description:
Currently, import_statements yields a name error if the class is not
imported in the Sage interpreter namespace. For example.
{{{
sage: import_statements(ClonableIntArray)
NameError: name 'ClonableIntArray' is not defined
}}}
With this patch, one can specify the object as a string, and the object
is looked up in all (imported) Sage modules.
{{{
sage: import_statements("ClonableIntArray")
}}}
See the documentation for more examples.
This patch implements several heuristics to better handle ambiguous
names.
