def safe_sympy_doit(a: Basic | MatrixBase):
    """Safely execute doit() on a sympy expression, catching exceptions.
      Doit in sympy will evaluate expressions it will pass the expression tree and evluate nodes.
      For example for 1+1+1 it will evaluate the additions and return 3. One issue with it is that it maybe
      evaluates too much as integrals will also be evaluated.
      As we are using latex2sympy2_extended, evaluates are lazy and only evaluated when needed.

    Args:
        a: A sympy Basic or MatrixBase expression to evaluate

    Returns:
        The result of a.doit() if successful, otherwise returns the original expression
