class Array

Converts array to proc with chained calls of items. Every item can be either a method name or an array containing a method name and args.

Examples¶ ↑

the_hash = { :one => "One", :two => "Two", :three => 3, :four => nil }
mapping = { "one" => "1", "two" => "2", "" => "0" }

the_hash.select(&[[:[], 1], [:is_a?, String]])
# => { :one => "One", :two => "Two" }

the_hash.values.map(&[:to_s, :downcase, [:sub, /one|two|$^/, mapping]])
# => ["1", "2", "3", "0"]
