I think I remember that this distinction was agreed on during a Jitsi meeting
some time ago.
"loop foreach" is intended for iterating across strings, and
allowing iteration over bundle keys and arrays of strings is a
special case of that. But in general "foreach" for arrays is
redundant since they are indexed and ordered.
