Comments
Single Line
Like in Perl 5 and many other languages of its league a "#" tells the compiler to ignore the rest of the line.

POD
Number Literals
Konverting into numerical context means still: take from left to right all digits and other characters, up to the first char that clearly don't belong to a number definition and stop there.
A single underscore is allowed only between any two digits in a literal number, like:
$people = 3_456_789; # same as 3456789
Radix Prefixes
0b binary - base 2, digits 0..1
0o ocatal - base 8, digits 0..7
0d decimal - base 10, digits 0..9
0x hexadecimal - base 16, digits 0..9,a..f (case insensitive)
General Radix Form
:10<42> # same as 0d42 or 42
Scientific Notation
$float = 60.2e23 # becomes automatically 6.02e24
$float = 6.02E-23 # capital E works too
Rational Number
Complex Number

Heredocs
Are now normal quoted strings, only with a special delimiter.
Q :to 'EOT';
...

EOT
To make templates in which variables and closures are evaluated, take the normal double quote and just add the adverb for the heredoc delimiter or define with other adverbs what exactly you want to have evaluated.
pp:to 'EOT';
