I find myself needing to run a method and if the method does not exist,
have it return itself, instead of nil quite often, I think this change
could be used fairly widely.
module ActiveSupport
module Tryable #:nodoc:
def try(*a, &b)
try!(*a, &b) if a.empty? || respond_to?(a.first)
end
# NEW METHOD
def attempt(*a, &b)
try(*a, &b) || self
end
end
end
