catch missing ^ references #13
Description
Here is the code:
[] > foo
[] > bar
^.hello > @
Obviously, this code has an error, because hello is not present in the foo object. We can detect this problem statically.
Here is a more complex example:
[] > foo
"yes" > message
[] > bar
while
[i] >>
if.
i.lt 5
QQ.io.stdout
^.^.messageeee # typo here!
true
true > [i]
We can detect this typo, I believe.
