I meant 'punctuation' instead of 'control word' for ) and NB. .

I didn't mean readable in the usual
why-can't-anybody-write-comments-any-more sense, but as a reference to
the Qt IDE's habit of treating quoted control words as active, and
giving the wrong font to everything that follows. Half a line can get
formatted as comments. If you actually DO have lots of comments, this
is hard to sort out.

readability issues are usually a call for better code.
For this, perhaps (warning: lightly tested code):
firstunmatched=:3 :0
q=. unquoted=. -.~:/\y=''''
c=. uncommented=. -. +./\ q * 'NB.' E. y
n=. parendepth=. +/\q*c*-/'()'=/y
if. 0 < {: n do.
(n i. _1) <. 1+1 i:~0 1 E. n
else.
n i. _1
end.
)
In other words: ignoring quoted and commented parenthesis, look for
the first occurrence of either an unbalanced right parenthesis or an
unbalanced left parenthesis.
Let me know, though, if you see any flaws in this implementation.
