|The stupid question is the question not asked|
You definitely won't have to write any OO implementation code, RPerl provides it for you, just like Moose does. The difference is that RPerl only uses low-magic OO and Moose does high-magic OO. RPerl's low-magic OO can be compiled into C++ OO, Moose and other high-magic Perl OO not so much.
The reason why this may have been confusing is because I do not mention RPerl itself anywhere in The Low-Magic Perl Commandments. This is because the LMPC are general guidelines to be followed by any low-magic Perl software, such as some of RPerl's sister projects under the Perl 11 umbrella, like Reini's P2 and Goccy's GPerl. So the LMPC don't require use of RPerl specifically, just low-magic strategies in general.
Does that help clear things up?
