George Peter Staplin: July 13, 2004 - Tcl 9.0 feels like something just beyond the grasp of reality. There are many ideas for what needs to be done, but most ideas from what I've seen aren't being actively worked on. I can't blame anybody for that though. We work on what we want to -- Tcl is free after all.
I've talked with Joe Mistachkin about JIT for Tcl 9.0. I've come to realize it's quite a bit more complex than my JIT for Forth, because of Tcl being so dynamic. I'm actively working on a prototype design.
Salvatore Sanfilipo and I talked about BigNum support. He even has some C code that implements such a thing. There is also: Proper integers for Tcl 8.5 or 9.0 and Proper integers implementation.
