I would like to replace the contents of the tag body with the error report.
Something like:

[ "proceses callback" ]
      on: Error
      do: [ : err | aScript element
id: (SUStream on: 'document.body');
 update:  [: render |  self reportError: err on: render ] ]

It is possible?

I guess using something like

Yes, I use it, but the problem is that I cannot inform users that an error
has occurred
