Re: setarray[unsetkey] doesn't trigger nounset in arithmetic context

[Martin D Kealey]

I just realised I expressed an opinion about associative arrays while the
original post was about indexed arrays.

My take on this is that indexed arrays are almost always "dynamic"; while
it's possible to use constant indices to emulate a struct, that is unusual.
For most purposes the flexibility in adding & removing from an array is a
feature, not a bug.

The support for missing elements or 'empty slots' is a bit unusual, but
once that's given, it's entirely predictable that "missing" elements are
just a normal kind of data, which is where I was heading with my suggestion
about non-sparse arrays.
