I think that, strictly speaking, we have no array dimensions in the string
'{{{{{{{{{{'; there are only characters (braces) during the string parsing.
While in the PLs we definitely deal with real arrays, which have dimensions.

Those messages looked more or less correct to me, I just wanted to note how they are
changing (and haven't highlighted messages, that are not), but if you see here room
for improvement, please look into it (I have no good formulations yet).
