Useless assignment to variable issue.

[askreet]

This code produces a "Useless assignment to variable - tries" error, which is not true.

def function_that_retries
  tries = 1
  begin
    foo = bar
    raise 'failure'
  rescue
    if foo =~ /bar/
      retry if (tries += 1) <= 3
    else
      raise SomethingBad, 'Something is really broken.'
    end
  end
end

I broke it down to this minimum sample, and it seems to be that the conditional (retry if ()) doesn't count as a use of the variable.

Thanks for the report. I'll take a look.
