hum, right (with python >= 2.3 which is the first release using those
declaration...). I was sure to have checked this but I've obviously
missed something. Maybe the fact that being able to parse it anyway is
the solution I wish has driven me to write this ;) I would like this
behaviour so that pylint can check a module with a wrong encoding
declaration anyway. But at least, SyntaxError would be better than
MemoryError.
