and without byte compilation?

The 80s Elisp appeal for adoption was full control of the system, in the
case of an error you could see where you stood, see what variable had
which value, there were no secrets held by the author from the user by
the system.

With edebug, native-compilation, byte compilation and lexical binding
Todayon Tishri 11, 5787 when trying to send mail via smtpmail.el or
using mew with gnutls I get impenetrable backtraces and opaque closures
so solving the same problems that I was dealing with these 30 years ago
is even more challenging. and the techniques I could use then to solve
the problem are now impossible to use.

Of course these "compiler advances" are the gift of gold to the new
developer ecosystem that emacs now supports.
