Feature request: field type "list:float" or "list:double"

The only databases I’m really familiar with are MySQL, and SQLite, but I can’t think of any technical reasons why a “list:double” type can’t work just like “list:integer” does. Seems like a bit of an oversight that there isn’t already such a type. It looks like I should be able to simply:

• Add a method bar_decode_double(value) in helpers/methods.py
• Add a method ListsParser._list_doubles(self, value) in parsers/base.py
• Add two methods, SQLDialect.type_list_double(self) and NoSQLDialect.type_list_double(self), in dialects/base.py
• Add two methods, BaseRepresenter._list_double(self, value) and NoSQLRepresenter._list_double(self, value), in representers/base.py

If there aren’t any technical objections, I’ll make a fork and start working on adding a “list:double” type, and then issue a pull request. If I’m missing anything obvious, let me know.

Let’s here some more opinions on web2py developer about this. If other developers disagree with me, I am not vetoing this. I am just explaining why I never needed and I tend to prefer not to add things that can be done in other ways.
