Subject: [ruby-talk:11648] Putting methods in arrays

Hi there,
  I'm looking to put a method in an array, to be called at a later time.  
In C, this is possible using pointers (through some rigamarole and 
typedefs, it would  look like { funct }).  Is there any way this can 
similarly be acheived in Ruby?
  What the end goal is to be able to call the method using 'arr[index] 
args'.  The purpose of this is that I'm working on a server that might 
receive one of hundreds of commands from the client side, and this:
  commands = [ [ "start", start_func ], ["end", end_func] ]
  for arr in commands
    if arr[0] == str
      command = arr[1]
      break
    end
  end
  command args
the last line 'command args' would then execute the command. 
  Is this possible?  Is there a better solution for command recognition 
without endless if/elsif/..?
  Thanks,
    Alex McHale, Daimun
