Comment (by Matthew Pava):
In regards to Left() and Right(), they are available in PostgreSQL and
MySQL, but not in SQLite or Oracle. However, you can emulate their
functionality using the corresponding Substr function in the database
backend. I would hate to see us leave those out for that reason alone.
At the same time, developers could use the Substr across all databases
instead of using Left and Right.
I was also wondering about the use of Trim. Python doesn't use that term;
instead, it uses strip. I wonder if that really matters. Some developers
may look for a strip functionality in Django ORM not realizing that the
databases use the term Trim. Perhaps that could be clarified in the
documentation.
