A Coq plugin that provides a tactic that iterates over various collections of terms. For example,

Create HintDb my_lemmas.

Hint Resolve lem1 lem2 : my_lemmas.

Ltac the_tactic :=
  let k lem := idtac lem in
  foreach [ db:my_lemmas ] k.
(* OUTPUT:
lem1
lem2
*)

There are three versions of the iterator

• foreach [ .. ] k combines the invocations of k using ;
• first_of [ .. ] k combines the invocations of k in the same way a first
• plus_of [ .. ] k combines the invocations of k using +

And there are several types of collections:

• *|- iterates premises bottom-to-top by default
• rev c reverses the iteration of c
• db:h iterates the hints inside the hint database h

Please submit bugs and feature requests to the github issue tracker.
