No, it was never thought necessary.

But I can point out that the function at the C level that builds the
errorcode builds a list from its arguments, and has been documented to
do so since... well, it's documented in the Ousterhout book, so that
makes it at least 15 years old. While strictly you can build it yourself
directly, nobody does.

See the 'tclvars' manual page for what formal information we have, and
'Tcl_SetErrorCode' for the constructor function.

Yes, and you've been one of the main sources of misinformation.
