Hmmm. What is a simple expression? Right now, translator assignments
are "simple", which doesn't fit my intuition. (They require a
semicolon.) This is perhaps the most shocking change in the semicolon
behavior. It took me a while to realize that
foo = 1.0
was acceptible with no semicolon. But it somehow seemed more natural for
foo = \notes{ . . . }
to be acceptible with no semicolon. It seems odd that
foo = \translator{ . . . };
needs that semicolon.
So is this the planned behavior:
Semicolons are needed precisely in the following locations:
after "simple" assignments
after keywords that require them
What is the gain of requiring semicolons after simple assignments?
Note that convert-mudela doesn't add the semicolons that are now needed
with mudela 1.0.6. For example, I always used to write
\paper{linewidth=-1.0}
and this is now an error which is not fixed by convert-mudela.

Well, of course I tried it before asking the above. And there is no
obvious effect. But there may be hidden effects of some sort.
If possible, it might be nice for a warning to appear if someone does
\translator with no name and without assigning it to an identifier.
In other words, forgetting the name seems to be a mistake that leads
to the wrong behavior with no warning.
I just discovered the \> \< and \! commands. I'm a bit puzzled,
though. Is \! just the same as \spandynamic{1 2} which is the same as
\cr and \decr? Why does
\notes{ a \< b \cr }
work but
\notes{ a \< b \! }
give a parse error?
