Subject: LogicalExpressionSimplifier rules
Sending this email for getting wider attention.
I propose disabling LogicalExpressionSimplifier optimizer rule, because
the complexity of that rule and number of bugs that seem to come from
there does not justify the expected performance gains -
In general, I think any new code that is significantly complex (ie hard
to maintain, and likely source of bugs) should be added to pig only if
there are enough gains to justify it.
