It is no wonder that Emacs is in such a poor state with 2 out 3
responding developers failing to make _one_ mental step from "while t"
to "this could be a 100-line loop that accidentally falls into
infinite recursion".  And even because of incompatible change in Emacs
itself.

Just wish I didn't get accustomed to this pile of crap 20 years ago
and just used a normal IDE like every smart person.
