the startswith/endswith functions are just sticking a "%" on either

could accept a bindparam argument since there is a string concatenation
that must take place within the python space.
Since the startswith parameter should be a string, you don't need to use
the + operator to concatenate, but...
>>> '%(oper)s%(literal)s' % {'oper': 'my', 'literal': '%'}
'my%'
instead of...
>>> '%(oper)s + %(literal)s' % {'oper': 'my', 'literal': '%'}
'my + %'
you should instead use
LIKE directly with your own bindparam that includes a "%" on the left
or right side of the string expression.
Yes, I know, but if I can use LIKE instead of start/end{swith}. I wonder
why we have those operators in sqlalchemy, with partial functionality? ;-)
