The "PHP6 fiasco"? A major featured release was too much, and had to be scoped down. Since then most stuff has been released as 5.4, 5.5 etc.
Did it break anybody's code? No. Did it divided the community? No. Did it halted PHP development? No. At worst, it make some prematurely released PHP6 books obsolete. Big fucking deal.
Compared to Perl 6 (still MIA for actual production development) and Python 3 (only 10% adoption or less after 5 years for an update that doesn't even offer that much), I'll take the PHP6 fiasco anytime.
>At some point , every big open source project team must make tough choices to make the project "future proof". Python team did it, Ruby is doing it,NodeJS will to be compliant with ES6 modules.
Python 6 did it badly, Ruby didn't do much, and NodeJS will have the ES6 modules "update" happen automatically by virtue of them being based on V8.
