This condition seems to be always false.
Did you mean to add another branch for ByteCodeArrays here?
Or IsAbstractCode check?

Opps, this should indeed be an '||', updated. This didn't cause any issue
because this is dead code (see comment above), maybe we should just delete this
whole function and the associated CodeDeleteEvent?

I would be fine with deleting the dead code.

[rmcilroy, 2016/02/25 15:06:54]

Dead code removed.
