New submission from anatoly techtonik <techto...@gmail.com>:
It is an error to try to inherit from function and the error message in
this case is:
{{{
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "m:\p\pb.py", line 4, in <module>
class PostgreSQLConnection(DatabaseConnection):
TypeError: Error when calling the metaclass bases
function() argument 1 must be code, not str
}}}
Something like 'Impossible to inherit from function' will clear
confusion state from users unfamiliar with metaclasses.
{{{
def DatabaseConnection(object):
pass
class PostgreSQLConnection(DatabaseConnection):
pass
}}}
