You're quite right - I'm not quite sure why I thought this would be
"scalar" context, but on reflection it clearly isn't. However, this does
give rise to a couple of questions:
1. What should we do if the array contains strings of more than one type
and/or encoding? Clearly we need to do some kind of transcoding, but how
do we decide what to transcode to? I've had a look in strings.pod but it
doesn't seem to be terribly helpful on this point.
2. Will the elements of PerlArrays always be scalar values, or can they
be aggregates (like other PerlArrays for instance).
