IRB Code

IRB (main):004:0> "Hello World"-SPL

= > ["Hi", "there", "Daniel"]
IRB (main):006:0> "Hi there Daniel". S
=> "ambigous abbreviation s->  Select, slice, sub!, squeeze, send, split,
size, strip, succ!, squeeze!, Sub, slice!, scan, sort, swapcase, swapcase!,
sum, Singleton_methods, SUCC, sort_by, strip! "

Ruby Code

Class Object
  def method_missing (name, *args, &block)
    candidates = Methods.grep/^#{name}/raise
    " Undefined method ' #{name} ' for #{self}:#{self.class} ' if Candidates.empty?
    Raise "ambigous abbreviation #{name}-> #{candidates.join ', '}" unless candidates.one?
    Method (Candidates.first). Call *args
  End
