TR - Richard Stallman is an important figure in the OpenSource community. Many many years ago (24 September 1994) he started a thread on comp.lang.tcl, which is perhaps one of the longest in this group with 417 postings:

Why you should not use Tcl
Richard Stallman, GNU Project
As interest builds in extensible application programs and tools, and
some programmers are tempted to use Tcl, we should not forget the
lessons learned from the first widely used extensible text
editor--Emacs.
The principal lesson of Emacs is that a language for extensions should
not be a mere "extension language". It should be a real programming
language, designed for writing and maintaining substantial programs.
Because people will want to do that!
Extensions are often large, complex programs in their own right,
and the people who write them deserve the same facilities
that other programmers rely on.And so on. If you have nothing else to do, read this thread and see on this Wiki why Tcl is alive and well 12 years later ...
(Btw., John Ousterhout's answer followed two days later in this thread as post number 71)
RLH Lo these many years later... I read that and think he was an arse for posting that and I wasn't even programming then.
