Feedback from Discord:

> I wish the Cairo compiler automatically handled things so that revoked references never arose.

> Also wish the Cairo compiler were faster […]  
> I think the reason I care so much about compiler speed is actually because of revoked refs — it’s time-consuming to wait to discover where the next one is. So if that issue goes away I might care somewhat less about compiler speed.

This issue should be solved in Cairo 0.5.1

Compilation speed was improved in cairo-v0.5.0  
revoked references were resolved from some of the cases in cairo-v0.5.2
