The primary feature of colorForth source is that it is preparsed, so 
that functions of the compiler are handled by the editor. colorForth 
source distinguishes not just between interpret and compile, but also 
between numbers and text. This is not simply a matter of character set 
ASCII vs. huffman.

Another Forth I have seen (herkforth), takes the colorForth concept a step 
further and builds the dictionary at edit time. The text of a word is not 
stored in source, instead and index is stored which corresponds with a 
dictionary entry. A dictionary entry holds, among other things, the 
text of the word.
