[issue37500] 3.8.0b2 no longer optimizes away "if 0:" ?

[Ned Deily]

Ned Deily <nad at python.org> added the comment:

For the record, this change in behavior was originally backported to the 3.7 branch and appeared in 3.7.4rc1 and rc2.  Now that the compatibility issues are clearer, it will be reverted for 3.7.4 final and will not be considered for future 3.7.x releases.
