Code generation relies on positive id()

[Alan Hoey]

When attempting to initially render a template I get a "can't assign to operator" syntax error. After the template has successfully rendered once it appears to work fine from then onwards.

Further investigation suggests that the problem is that there are multiple places in translation.py where variable names are generated using for example "_attrs_%d" % id(self.element)). If the result of id is negative, this creates an invalid name, which ultimately causes the error.

I am seeing what appears to be the same issue when running Pyramid's test suite on PyPy 1.9.0 on Ubuntu.
