Nearly all transitions labeled.
All the transitions have been labeled with actions,
but one,
the transtion on <
from the "word" state to
the final state.
The <
signals the end of the word token being built,
but will also be part of the next token, and so cannot be discarded.
The <
must be pushed back into the input stream so that it can be
read the next time the transducer is called.
Mentally label the transition.
