A) It's released with a frozen spec and a large test suite for compliance (https://github.com/perl6/roast), with a compiler available that supports a module ecosystem with over 700 modules (http://modules.perl6.org). What's a complete state in your mind? If not this.
B) All of the below is core language, not a use or import anywhere required. Error reporting is also handled for you without autodie and friends.
Reading from a file:
#Efficiently line by line for STDIN
for lines() -> $line {
$line.say;
}
#Get everything in RAM right now
my $string = "filename".IO.slurp;
#Lazy list will do IO as you request into the list
my @lines = "filename".IO.lines;
#Listing of directories if the path is a directory
my @directories = "coolstuff".IO.dir if "coolstuff".IO.d;
Playing with dates:
#Get a DateTime for right n
Read the rest
ow
my $date = DateTime.now;
#Does what it says on the tin
say "Yippee" if $date.later(:5years).is-leap-year;
