For a *recognizer* the {...} action rules aren't needed, so removing them
for that purpose makes complete sense.  Thanks!

However, we also need to state what the rules *transform* an expression into.
So just like SRFI-49, I intend to express them as transforms in the formal grammar
in the final spec.

I will say I really like having the tutorial in the front of the SRFI.
One side-effect is that we can focus on rigor in the spec, since we no longer
need to also explain its purpose.  I suspect some other SRFIs might benefit
from a short tutorial near their front.
