There are situations where what is needed is to extract different
things from a large JSON and do something with the values. Having to
make a difference between, say, v:true and 1 would propagate all over
the place, because:
:echo v:true == 1
1
but
:echo [v:true] == [1]
0
and
:echo [v:true] is [1]
0
