I'm working on implementing Tcl (http://www.tcl.tk) from scratch on top of parrot (http://www.parrotcode.org). The code so far is available as part of the parrot distribution.
I've spoken briefly with some of the folks on the Tcl Core team, who suggested that this version of Tcl be called "ParTcl" ... which is so bad, I'm going to have to use it.
Right now, I've got a big chunk of the interpreter working. Next two big steps are overhauling [expr], and swapping out the generic (and Perl) PMCs for dynamically loaded Tcl PMCs. Now that Parrot 0.1.1 is released, I should be able to switch over to the dynamic PMCs without a problem.
Once those are done, I can add in/flesh out all the tcl builtins that rely on lists and arrays. (Or, if you speak perl, arrays and hashes. Mostly).
Volunteers welcome. ^_^
So, are the "other" versions (the duals) called waves?
