Strings and Numbers *ARE* objects just like any other. They just
happen to be created in C code rather than Io code. You can manipulate
number objects just like any other.
Literals are sent to the Lobby, which is unlike other objects in that
given: foo 5 <-- 5 won't be executed in the context of foo, like: foo
bar <-- would, 5 will be evaluated against the Lobby. Special case,
but that's how things are.
