Well I think it is not possible what I wanted to achieve. By overriding the "and" and "or" keyword I wanted to return a new object: SqlValueInt(4) and SqlValueInt(5) --> SqlOpAnd(SqlValueInt(4), SqlValueInt(5)) This is only possible for: +, -, /, *, >, >=, ... Well... I have to live with the (binary) __and__, __or__ option and the user has to write: SqlValueInt(4) & SqlValueInt(5) --> SqlOpAnd(SqlValueInt(4), SqlValueInt(5)) Thanks for your input, but __nonzero__ is not of any help in this case... I want to abuse the "magic" functions for some transformations and not some evaluation. Marco -- http://mail.python.org/mailman/listinfo/python-list
