wdb --- My first experiences with OO extensions in Tcl/Tk was Itcl which I used intensively on programming my CMS One Hand Content. This extension worked mostly as expected – with a few pitfalls and one thing I found annoying: options were mapped to internal variables of the objects. More than once I ran in danger of name collision inside method definitions.
Then, I found Snit and really enjoyed it. Especially, options are mapped to key/value pairs of an array. No more danger of name collision! — Instead of heritage, components are installed where methods and options can be delegated to: really great! — But, I found the hint that performance disappoints if there are many once-used local objects. But that was exactly what I wanted in my current project on computer-generated cartoons.
So, I made obj [L1 ] — just another OO system. It does not seamlessly fit into Tk's object approach, and it is far from being complete. But it is minimalistic, and it is (at least intended to be) quite fast.
