another random person learning TCL by throwing all my problems at it.
Some things I like about Tcl:
There are only 12 rules
Simple GUIs via Tk
Simple Client/Server
The Virtual File System
Isolated and safe child interpreters
Things written in Tcl
Expect: Control everything
Simple Databasing
Source Code Repository (in a single file)
Simple Wiki (this wiki. Single-file version)
etc
Other Stuff
Some pages I want to look at later
