Re: Bug with logical operator or misunderstanding?

Hmm, we're not there yet.  Your patch 5.1.4 yields the correct results

for these two cases:

Thank you to point out my mistake.  I forgot that 'nil' is equivalence 

to 'false' in the logical operation.

 

assert((((1 or false) and true) or false) == true)
assert((((1 or 2) and true) or false) == true)
assert(((nil and true) or false and true) == false)

assert((((nil and true) or false) and true) == false)

I fixed the patch to clear these cases.  Is it enough test case for this problem?
