I typed `100+88/4` and the resulting output was `100884+/`. Should the algorithm be inserting a symbol to delineate operands?

It treated that as

    1 0 0 + 8 8 / 4

which is nonsensical, but it has no error detection so it rolled with it. Really `100` should be its own token, but there's no way to input that.

How would one typically implement this tokenization? Pre-pass on the input? My initial thought was to push an operand-terminator token when encountering an operator, but it was unclear to me whether it should be pushed to the stack or the output.
