oh, its hideous. Especially when hardware design engineers write it. No tests, no real comments, just code that didn't work commented out. For all of the flack PHP receives, TCL is a hammer with the steel claw removed and replaced with a picture of a butterfly.
Yeah, I'm a hardware engineer, and I've come across code like that! But it's not Tcl's fault that hardware engineers can't write code, or even comments to go with the code.
