class Symbol
# Turns the symbol into a simple proc, which is especially useful for enumerations. Examples:
#
# # The same as people.collect { |p| p.name }
# people.collect(&:name)
#
# # The same as people.select { |p| p.manager? }.collect { |p| p.salary }
# people.select(&:manager?).collect(&:salary)

Proc.new { |*args| args.shift.__send__(self, *args) }
