Rod wasn't necessarily presuming that /usr/bin/perl would _commonly_ be the new Perl interpreter; but if somebody _does_ set up a computer in which that was the case, it ought to do something and preferably DTRT. But I'm guessing there's nothing special about the name /usr/bin/perl, and that invoking the interpreter by any name that isn't perl6 or any other declared 'special' name goes for the behaviour you explained of assuming Perl 5 until it encounters one of the constructs such as a bare C<my;> that persuade it otherwise.
