There is no point to using an MStatus and calls to CHECK_MSTATUS_AND_RETURN
here. None of your function calls ever accept a status to ever change its
state. So you are just checking the state of the default constructed
MStatus every time. However, the default constructor for MStatus should
initialize it to kSuccess which should make the check pass each time
anyways. So I am not sure what you mean when you say it returns "false". It
should just make it to the end of the function and return your MSyntax as
expected.
