To this day 'uplevel' is still one of the more bonkers things I've seen in a programming language.

Are you sure? Uplevel enables various metaprogramming techniques with far less weird magic than C++ requires!

I have no criticism of it, it just feels like a different evolutionary path versus my journey to as-pure-as-reasonable FP.

Most metaprogramming can probably be described as somewhat bonkers!

Yeah, ADL says hello. Basically dynamic scoped variables from Clipper/Lisp/Perl, with types into the mix.

I found it very handy.

Tcl has a special place on my heart, with our AOLServer clone back in 2000's.

Back when us, AOLServer, Vignette and a couple others were already doing application servers.

However lack of JIT, was really an issue. We rewrote plenty of stuff into C.

Who is the "we" you refer to here?

Intervento,a Portuguese startup that was already doing "Rails" with Tcl back in the dotcom wave, but Lisbon isn't Silicon Valey.

The founders eventually founded OutSystems, based on our experience doing our AOLServer clone, and being one of the Portuguese partners with alpha access to what would become .NET.

OutSystems was founded on the same principle thar doing Websites and integration should be RAD/Low Code experience, just like we were doing with our Tcl based application server.

This is still just the first beta release, 9.0 final is a few months away.
