This is nice! 

Smalltalk actually got started by thinking about a way to make a child's 
Logo-like language with objects and pattern matching that could express its own 
operating system and environment.

It is very tricky to retain/maintain readability (so the first Smalltalk was 
also an extensible language not just semantically but syntactically). 

With a tile language, this is really worth thinking about, since using tiles 
suggests ways to extend both the form and the meaning of the tiles.

Subject: [IAEP] Turtles All The Way Down

I've done a little more work on "Turtles All The Way Down", which I
(very briefly) discussed at EduJam.  I actually wrote a garbage
collector in TurtleScript for TurtleScript on Sunday.  Brief writeup
and exhaustive mind-numbing detail here:

No actual turtles yet!  I'm going to have to fix that soon.
