There is at least one external goodie that provides non-intrusive 
highlighting (i.e., without pretty-printing).  I inherited the Squeak 1.x 
changeset from Martin Wollenweber and carried it through to Squeak 2.x, see

<http://home.netsurf.de/helge.horch/squeak/syntaxcol.html>

Squeak 3.1a, that changeset currently lives at
