Why is this a bug? (Not to mention why is it "serious"!) Why should the
precedence rule for parameter names (which are, after all, variables, be
different from those for any other variable?
What would your co-worker have it do instead?
Yes, it's a gotcha. But there are lots of others, as there are with any
language. We might try finding out why it works the way it does before we
start hurling the 'b' word around.
