Sorry, apparently hit Send too soon.

Now, imagine that instead of the 2->3 transition you brought up, you
instead wanted to achieve something like this:


In the existing template, it's a change of one letter (an "x" became a
"y").  In yours, it's a major change to the template, requiring it to be
rewritten as "ab(xr/y(t/u))" (for reference, the (2) template was

Whether a change is large or not depends on the change.  I think both your
2->3 and my 2->3b transitions are plausible.  However, I think that the
"bad" case for the ascii template is better than the "bad" case for your
fraction-bar template.  At the very least, the badness of the fraction-bar
template when doing the 2->3b transition shows that it's not an immediate
sale, even if you think it's readable.

I believe that in *most* simple cases, both systems are about equally easy
to work with.  For the rest of the simple cases, one or the other is better
depending on the details.  In complex cases (where the slots aren't set up
in easy, proportional ways), the ascii template is usually easier.
