Declare Implicit Tactic (eauto with nocore tcinit_db; shelve).

Yes, that could be a winner.

Although now it looks like Declare Implicit Tactic has some bugs. The declared tactic doesn't get called in all the cases it claims: "It is used every time the term argument of a tactic has one of its holes not fully resolved.". For instance, "refine _" doesn't call it.

And in one case, it is giving me: "Anomaly: Evar ?X96 was not declared. Please report."

On second thought - it seems easier to get Declare Implicit Tactic to fail than to succeed. I guess nobody uses it.
