Short answer: Extremely rarely.
Slightly longer answer:
If my application ran/tested cleanly with use strict, but the operational requirements were such that disabling it allowed those ORs to be met without further modification, when they were not met when it was in force.

My answer: I have yet to encounter one, but if I did, I would consider the option.
Examine what is said, not who speaks.
1) When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong.
2) The only way of discovering the limits of the possible is to venture a little way past them into the impossible
3) Any sufficiently advanced technology is indistinguishable from magic.
