Oh, so to clarify (kind of making the bigint library up):

t = {}
t[x] = "booya!"
print(t[y])
booya!
In this case __key would help at all. With or without it you'd have to keep
a cache of these values, because it's needed to make __key return the same
object. So, it's easier to make bi.make return the same object for both
calls instead.
That's not true at all. bi.__key could return a Lua "number"-type
value when the value is representable without loss of precision or a
string otherwise. This would provide for the nice property of
"t[bi.make(100)] == t[100]" in addition to the "t[x] == t[y]" desired
in the example.
