I'm not sure that conversion from a Python type to a buffer object are
that transparent.  For instance there seems to be no straightforward
way to represent 3.141 as a sequence of bytes backed by a buffer in
Python (or accessible via the buffer interface rather).  Maybe there
is, I'm certainly not a Python language expert.  I hope someone can
prove me wrong!


Right now with the existing code, we take 3.141 as a gdb.value and
convert that to bytes via value_contents. Your suggestions would
certainly make the existing code simpler (and my porting task a little
easier ;), but I can't help thinking that it would be just making the
user jump through extra hoops just for API pureness.  I strive for
that, it's a good thing; it just strikes me a little too much in this
case.  OTOH we could just make add_value_pattern available via the API
and have the user manually do the conversion "the GDB way".

Sure, will do.
