 There is also, in tcllib, the 'cmdline' package:
 https://core.tcl-lang.org/tcllib/doc/trunk/embedded/md/tcllib/files/modules/cmdline/cmdline.md
 Which provides an options parser that is very similar (although not
100% identical) to the GNU C 'getopt' options parser.  And the man page
has an example.

It looks like a recipe for a unix command line, not so much a tcl command.

 Quite a number of other tcllib modules use 'cmdline' for their options
parsing, so it is 'reasonably standard' in that sense -- and being very
similar to the gnulib C 'getopt' library function makes it much more
'standards like' (assuming one considers C library functions to be
'standard') than most.
 

I suggested that one could "parse" a Tcl command spec a-la the manual's standard, because it should be familiar to all Tcl programmers, or at least those that RTM :)
Also it was quite easy to build a working ad-hoc program using chatGPT from just such a spec. If it becomes so complex that it can't do it, then it's likely going to be too complex for humans as well.
