coq-ltac-iter

=============

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```
