I haven't seen the loki documentation, but maybe I should have a look
at it. I have to agree with you about the documentation being hard to
follow - mostly, it makes sense only once you've already figured it
out some other way. The trouble is probably that it is written mostly
as a reference instead of being a tutorial or user guide. Both types
are important to have, IMHO.

Well, that's actually not too hard. I haven't yet documented the
iterator_pair template, but you can probably figure it out from the
the getArray function in libs/python/test/testlinear.cpp

BTW, the suite definitely wants to know how long the array is. If you
really want to disable the bounds checking, you could probably just
pretend that the array is "really long" by adding a big number to the
start address.
