Did a lot of low hanging fruit - builtins that we had already implemented, but needed slightly different error messages, or that we hadn't yet written a test for, or were otherwise borked.
Also committed some udpates to the script that generates our tcl tests, making it more verbose so one might figure out what's going on while it's running.
Oddly enough, we're passing a test here or there for builtins we haven't implemented. That can't be right. =-)
Matt is going to implement [lindex], which would give us some more easy passes.
I've pinged the list about getting PGE to support character classes, which will help any failing [string match] tests.
Current passing percentage of tcl's tests (not including [clock]): 12.00%
