I reported this as a bug because if I compile the final classes (with `toat' instead
of `stoat') from scratch, the Flat form of TEST1 looks correct.  I understand that
it may not be possible to produce a reasonable Clickable or Flat form if
compilation did not succeed, but since estudio was able to do so in
the case of a "from scratch" compilation, I thought it should be able to do it
after an incremental change as well.

Also, the compiler seems to know that `toat' is an attribute since it shows it
in the Attributes format, which indicates (from a naive point of view anyway)
that it ought to show up in the Clickable format.
