 I guess your contribution to the TCL code base would probably be
welcome, provided there is agreement on the necessity of this
feature...

The problem is always "time" … I work with a dozens of languages and TCL is just one of them…
for example today I figured out how to implement this in python…
def MkErrorC_FormatException(err,exp,caller):
   err.NoRaise().SetC(str(exp),caller)
   tb = exp.__traceback__
   while tb is not None:
     err.StackFormat(
       tb.tb_frame.f_code.co_qualname,
         tb.tb_frame.f_code.co_filename,
           tb.tb_lineno
     )
     tb = tb.tb_next
and by-the-way I add a feature to direct "inject" python-code into a python-c-extension without
shipping an extra python source file.
