It's one thing to not constrain Perl6 to back compat and another to create unnecessary confusion by arbitrary operator and sigil changes. No the result is not more friendly, the result is more confusing. It's like Russian to a Czech. Yeah the languages have lots of similarities, part of the vocabulary, the declination system ... which means that Czechs use Slovak words with Russian accents in cases where the Russian word is completely different, they use word that sound similar, but mean something completely different, waste time trying to remember a word when pronouncing the Czech one in Russian accent would be correct, they decline all wrong, because while the declinations are deceptively similar they are also different etc. etc. etc.
All this doesn't matter that much when speaking to a human being (unless that being is a teacher), communication with a compiler is much less forgiving and when combined with your hailed two kindaPerl5s this just creates an insane mess.
You can use @ for arrays in the STD language of Perl 6, but you don't have to
So what's the difference between $array and @array then? Sigils are a perfect example of an absolutely pointless and confusion generating change. Imagine you are new to all this and you ask uncle Google what the heck do those $s and @s and %s mean ... you get contradicting answers!
The toolchain eventually created by this project may end up being used for something, but so far it has hurt rather then helped Perl.
Enoch was right!
