## Match Regular Expression to one or multiple strings
class Regexp
  def to_proc
    proc { |arg| arg.to_s[self] }
  end
end

## USE CASE ##
params = ["Imagination", "is", "more", "important", "than", "knowledge."]
params2 = %w|Quote by Albert Einstein|

p params.map &/or/
# => [nil, nil, "or", "or", nil, nil]
p params.select &/o|r/
# => ["Imagination", "more", "important", "knowledge."]
p params2.select &/[or]/
# => ["Quote", "Albert"]

## Reasoning ##
# This simple implementation makes matching agains an array of strings effortless
# From Symbol#to_proc, a developer can easily guess what Regexp#to_proc might do
