Assuming you are suggesting your examples are showing differences
between the languages, in all your examples of differences between Perl
6 and Perl 5 below, you are using the wrong operator or you changed one
of the arguments between the Perl 5 and Perl 6 examples.
I won't go through them each, but for example '> 3' is the greater-than
operator in Perl 5; 0b0001_0100 (20) is greater than 3, so the answer is
1 (true). And in your bitwise shift left, you're shifting by 2 in Perl 6
but by 3 in Perl 5. And so on.
Hi Trey,
Ah poop! I made another booboo. Mumble, mumble.
corrected:
$ p5 'my $v = 0b00000100 << 3; say $v;'
32
This is my own reference. I do still maintain a few p5 programs
so I was writing a one size fits all.
Thank you for the catch!

My Keepers is basically a directory by subject:
perl6.String.to.Integer.txt
perl6.string.words.example.txt
perl6.string.zeros.remove.leading.txt
perl6.subroutines.passing.arrays.and.hashes.html
perl6.subroutines.txt
perl6.subs.calling.ones.self.txt
perl6.subs.name.of.sub.txt
perl6.succ.successor.txt
perl6.syntax.check.txt
perl6.syntax.txt
145 of them now. They are my first line of reference when programming.
For instance: perl6.String.to.Integer.txt (notice how I start
simple and them more up):
Perl 6: convert String to Integer and Integer to String:
String to Integer:
$ p6 'my Str $x = "122333"; my Int $y = $x.Int; say $y;'
122333
$ p6 'my Int $x; my Str $y = "5"; $x = "$y" + 0; say "$x";'

Integer to String:
$ p6 'my Int $x = 122333; my Str $y = $x.Str; say $y;'
122333
$ p6 'my Str $x; my Int $y = 9; $x = "$y"; say "$x";'

$ p6 'my Str $x = "1\n22\n333\n"; my Int @y; @y = ( split "\n", $x,
:skip-empty )>>.Int; for @y -> Int $i {say $i;}'
