Uberscore

Born to make your Ruby blocks more concise.

# Chain method calls.
%w[0x 0d ea].map { |element| element.hex.divmod(13)[1] == 0 } # Without Uberscore
%w[0x 0d ea].map(&_.hex.divmod(13)[1] == 0) # With Uberscore

# Use class methods.
[Array, Hash].map { |a_class| a_class.new(4) }
[Array, Hash].map(&_.new(4))

# Nest.
[[2, 3]].map { |array| array.map { |element| element * 2 } }
[[2, 3]].map(&_.map(&_ * 2))

# Subscript.
[{ name: "foo" }, { name: "bar" }].map { |hash| hash[:name] }
[{ name: "foo" }, { name: "bar" }].map(&_[:name])
