Summary: bit shift operator << precedence
Initial Comment:
In 2.1.1,
It appears bit shift operator << has lower precedence than operator +. Expression 1<<16 + 1
results in 131072 rather than the expected 65537. User has to use (1<<16) +1 to get the
expected result.

Alas, Python doesn't yet parse whitespace in expressions.
:-)
According to the Python reference manual, << has indeed
lower precedence than +, so this is not a bug.
