IBM 7030 did something like the latter, but neither is right; it's worse.
An example:
1234
camel
Camel
CAMEL
canary
Canary
CANARY
cat
Cat
CAT
... Note that "CAMEL" comes after "Camel" but before "canary". So you can't
simply say either that A<a or A>a.
But would you argue that computers should scorn English lexical conventions?
