But beware if you talk about "context" to a core developer he might
misunderstand you.
In core there's a special context datastructure, the cx, storing scope
information.

This article is talking about "gimme", if scalar, list or void (return) context.

This is a very good one.
Note that p5p just discussed the addition of a count method for arrays
and lists,
to get rid of the misleading name scalar @array,
and to do the right thing for count(@a, @b);
