% dict set tst a b c d
a {b {c d}}
% dict exists $tst a b c
1
% dict exists $tst a b c d
missing value to go with key

The last command throws an error; since d is a value not a key, I expected simply to get a return value of "0".

The one problem with this is that it makes it harder to know when you've done something silly like going too deep in a dictionary. Still, I buy the point that based on the current documentation it should not be throwing errors.

Fixed for 8.5 and 8.6

[00:14]SEHexpected simply to get "0"
[00:14]SEHbug?
[00:16]venksSEH - exists is for a key
[00:16]SEHright, but since d is not a key I expected to get "0", not an error
[00:16]venksah.
