Good question.
My gut tells me not to try and make the regexp more complex.

i've been trying every once in a while to figure out a solution to this
bug but keep failing.
@Stefan i've added you to cc: in case you can help a bit and provide
some tips.
In the fix for #39277 you've added tcl--syntax-of-quote and also this comment:
(defconst tcl-syntax-propertize-function
;; FIXME: Handle the [...] commands nested inside "..." strings.
so my question, is the problem described in this bug report supposed to be fixed as
a regexp in the tcl-syntax-propertize-function rules list or should i try
to extend tcl--syntax-of-quote to cover this case too? I've failed in
both accounts so far, especially the regexp i can't find the proper
pattern to fix this and not break something else (which kind of proves the
saying "you fix 1 problem with regexp - you now have 2 problems" :)
thank you in advance,
Michalis

After the applied fix in #39277, font locking fails in the following case:
set a "Testing: [split "192.168.1.1/24" "/"] address"
the last bracket ] reports "no matching parenthesis found"
this part:
192.168.1.1/24"
is not locked as a string, but "/" is.
Note that the whole argument is evaluated properly by tclsh as a
single contiguous string:
% set a "Testing: [split "192.168.1.1/24" "/"] address"
Testing: 192.168.1.1 24 address
i can't find a way around this behavior even with escaping the double
quotes or using single quotes, because doing that will change how the
argument is evaluated by tcl (array instead of string):
% set b "Testing: [split '192.168.1.1/24' '/'] address"
Testing: {} 192.168.1.1 24 {} address
% set a "Testing: [split \"192.168.1.1/24\" \"/\"] address"
Testing: {} 192.168.1.1 24 {} address
%
--
there's also another case of font locking failure, unrelated
to the #39277 changes:
puts {#test}
anything following # until end of line is locked as comment. But this
one is ok:
puts {a#test}
the inner a#test string is not locked as string but at least the
open-close brackets are marked properly.
