Feature Request: Give explicit examples of using for:for

[jgarte]

It has the other advantage of having one construct that works for all data structures (lists, vectors, hash-tables…): in doubt, just use for… over:

Let's give some explicit examples of using for:for and not this:

(for:for ((x over <your data structure>))
   (print …))

The above is not as friendly for new users who are not yet familiar with the syntax for common data structures and might even be confusing with a non standard syntax of <your data structure>. Let's make it friendlier.
