In a function I'd like to temporarily say

foo[x_]:=Module[{...},
  ...
  SetOptions[RowReduce, Method->OneStepRowReduction];
  ...
]

without affecting the global setting for RowReduce when I call foo.

My experiments wrapping the SetOptions with a Block structure were not
fruitful so far.
The only thing I can think of is something of the form

  method = Options[RowReduce, Method];
  SetOptions[RowReduce, Method->OneStepRowReduction];
  ... do something ...
  SetOptions[RowReduce,method]

But that looks ugly.

Any suggestions with built-in Mathematica features to achieve this kind of
locality.
