-------------------------------------

Seems like a reasonable proposal from back in Nov 2019.

I suspect it was discussed on the dev-list. I'm curious, Mr. [~cbrisson], what was the consensus opinion and action to take?

> `#foreach($x in $map)  defaults to iterating on map values. But what if we have to iterate on keys or on entries? Resorting to write #foreach($k in $map.keySet()) or #foreach($e in $map.entrySet()) always bothered me. Most of the time with maps, we'll want to iterate over keys or entries.
> The proposal is to introduce optional postfixed modifiers in the #foreach syntax, as follow:
> #foreach($k in $map entries)
> #foreach($k in $map keys)
> #foreach($k in $map values)
> the default being kept on values, as it is today. Applying the modifiers on anything else than a map would give an error.
