Having actually tried to learn this language, I'm astounded by its pattern matching facilities. Makes grep look primitive. 

Being a slow starter with tcl, where would I start trying to 
  1. write a snobol interpreter in tcl, or
  2. write snobol pattern matching tools in tcl?

''[escargo] 30 Dec 2003'' - I will just note that the successor to Snobol,
[Icon], also has a page on this wiki. It's pattern matching is different
than Snobol's, but also very powerful.  It is ''not'' based on regular
expressions, but does pattern matching with other facilities.
