I've read various articles and comments on how to implement class-methods
and class-variables in Tcloo, but I've never figured out how to implement
a class-constructor (similar to Snit's typeconstructor)
to initialize these class-variables.

Please, can you give me some simple examples ?

There is a simple example in the documentation of classvariable(n):

https://www.tcl-lang.org/man/tcl9.0/TclCmd/classvariable.html

The initialise/initialize command itself is documented in oo::define(n)

That's simply good !
I never considered these new Tcl9.x features, since I always tried to deliver code running for Tcl8.x and Tcl9.x.

After seeing how it works for Tcl9, I think I'll abandon full Tcl8.x compatibility, because trying to implement classmethods and classvariables with Tcl8.x is simply impossible, unless you resort to very complicated tricks
, with many limitations.
