[pypy-svn] rev 655 - in pypy/trunk/src/pypy/module: . test

New Revision: 655

Added:
   pypy/trunk/src/pypy/module/test/test_apply.py
Modified:
   pypy/trunk/src/pypy/module/builtin_app.py
Log:
Wrote trivial unit test for apply.  This assumes that if it ever works, it
always works, which is true because apply is just a synonym for 
return function(*args, **kwds).  However, if * or ** are broken, somebody
else will have to discover this.  This unit test is too trivial.
