Yes, I am. You made the unsupported statement that array operations are
rarely used. I'm suggesting otherwise (although to say that they're rarely
used in Perl 5 is a tautology, of course!).

That's not what RFC 82 is proposing.

That's because few such languages provide strong general purpose programming
features as well. They are either limited maths-oriented languages (like
Mathematica) or add-ons to general purpose languages that aren't fully
integrated (Python/NumPy; Perl/PDL; C++/Blitz++).

Many Perl users operate on lists of data. Requiring explicit loops every
time a programmer wants to operate on a list is asking the programmer to fit
in with how a computer thinks. That's not right.
