Ah, I was fooled by the message about Beautiful Soup. It is not a message of an
error, it is a part of source line, printed for a SyntaxError. Seems sources of
Beautiful Soup intentionally contain a code invalid in Python 3.
There is a bug in Python. The tokenizer returns error E_OK, but it should never
return such error code. The AST parser is confused and raises a SyntaxError
with the message "unknown parsing error".
This bug is reproduced when run Python wish both options -3 and -We and parse
the "<>" operator.
$ ./python -3 -We -c '[] <> []'
error=10
File "<string>", line 1
[] <> []
^
SyntaxError: unknown parsing error
But it is reproduced with 2.7.14 too.
