Try block

[raggi]

Add support for Object#try to just invoke a block if no method to be called has been given. This replaces the need for other hacks like unless_blank? { code } and if_present? { code } off of an existing method and paradigm.

Example:

@person = Struct.new(:first_name, :last_name).new("David", "Heinemeier Hansson")
@person.try { |p| "#{p.first_name} #{p.last_name}" } # => "David Heinemeier Hansson"
