(0) Someone will tell you that you can define whatever classes you like with
whatever index semantics that you like. It's all very well to *say* that things
would be better if one could change the lower index bound at will, but you have
the ability to *show* us, so why don't you? Try it out! Work out the inevitable
kinks with writing generic code that is agnostic to the heterogeneous index
semantics. Show us the code!
