It's not a definition but an assignment, and the assignment is not
"lazy" but executed as soon as it is complete.  Recognizing its
completeness may require examining the type of the next token, and the
type of $ depends on its value (which consequently needs to be evaluated
to figure out its type) while the type of # doesn't.
