Hi Adam. There's only one thing I don't understand:
a = 1; [2].each { |;a| p a; }; a #=> nil; 1
a = 1; [2].each { |;a| p a; a = 2; p a }; a #=> nil; 2; 1
This is the first time I've seen a variable passed into a code block
with a semicolon preceding it
|;a|
and also semicolon following the variable
p a;
I'm not sure what it does nor do I understand its significance. =)
