390749 [k.dorsel gma] Let's look at the Array class and start with method aliases.

390808 [cremes.devli] I would like to solve a problem where a writer of a class can provide an array of fields and those fields are turned into two things.

+ 390821 [transfire gm] I find writing an issue up often helps me figure out a problem, so it's not
  390837 [cremes.devli] Quite true. Perhaps my "thinking out loud" in public has been helpful for someone else too.
  390860 [pete peterhi] If it's not important to output the constructed string, you could do it
  390884 [cremes.devli] Pete, thanks for figuring out another approach. I prefer building a string and eval'ing it because it's easier (IMHO) to verify that the generated code is correct by examining the string. Using #define_method works quite well too, but when something is wrong with the method definition it's a bit tougher to track down and fix.
