Percent Notation
Ruby has many uses for the % character. One of the more obscure uses is as
a notion for custom delimited strings. Use the percent notation with a
non-alphanumeric character to surround a string.
> %=Jurassic Park=
=> "Jurassic Park"
> % Ghostbusters
=> "Ghostbusters"
It even works with balanced characters
> %(The Goonies)
=> "The Goonies"
This is useful for defining a string that has both types of quotes
> %[That'll be the "day"]
=> "That'll be the \"day\""
It's also useful for creating horribly obfuscated code
> %=what===%?what?
=> true
