I can reproduce this in Emacs 27, but it has been fixed in Emacs 28.

This is still present in Emacs 28.

Hello, I have found the following problems in tcl-mode, examples show how Emacs
indents them and what text I get with tcl-explain-indentation set to t
(when relevant):
* Indentation after declaring a proc goes to column 0, example:
namespace eval myns {
	proc p1 {} {}
variable x
proc p2 {} {}
}

"Indentation type nil" all along

* Mismatched parentheses when quoted:
puts {hel[lo}
puts {hel(lo}

* Procs named ? , ' or ^ botch indentation (thankfully only inside):
proc ? {} {
	    puts hello
       }
puts world

"Indentation type tcl-expr" for these,
"Indentation type tcl-commands" for other proc names.

Sorry if I can't offer a patch, my elisp skill and available time is basically
nil. The comment associated with the `defconst tcl-omit-ws-regexp` line seem
related to (3).
Obviously, only (1) and (2) are really annoying, basically forcing me to use mg
for Tcl.
