Tcl, or the “Tool Command Language“, created and released by John Ousterhout in 1990, deserves a place among the greatest products of the human mind. Especially when combined with its better known graphical user interface Toolkit — Tk. In 1997 Ousterhout was awarded the ACM Software System Award for Tcl/Tk, an award given to institutions or individuals recognized for developing software systems with a lasting influence, reflected in contributions to concepts, in commercial acceptance, or both.

Everything you could ever possibly want to know about Tcl/Tk. There’s nothing to add here; if this is up your alley – and you know if it is – just go ahead and read it, and stop wasting time here.
He did remark on C# CLR high RAM overhead but didn’t bother to use Native AOT compilation.
Maybe it wasn’t convenient for his comparision to one of the greatest products of the human mind.
