I could give a warning, but I think the false-alarm ratio would
be too high for it to be useful. There would often be
dozens or maybe hundreds of variables that might potentially
be overwritten as a result of a function call. It's theoretically
impossible to always know at compile-time whether a given variable
will actually be overwritten at run-time. In many cases the
potential will seem to be there, but in reality it will not happen.
