             Summary: Handle name conflict for overridden built-in and converted PyDML function
                 Key: SYSTEMML-696
                 URL: https://issues.apache.org/jira/browse/SYSTEMML-696
             Project: SystemML
          Issue Type: Bug
          Components: Parser, PyDML
            Reporter: Glenn Weidner


An error occurs if a user function definition overrides a built-in function for converting different PyDML syntax.  For example:

X = random.normal(4, 3, 1)
print(sum(X))

def rand(x: int) -> (y: int):
    y = x*2


org.apache.sysml.parser.LanguageException: Unsupported Parameters : ERROR: line 2, column 6 -- Expecting matrix parameter for function SUM
