Hi there,

Thanks for the feedback so far. :-)

"PROFILE IT!!!

everything else is BS."

As for profiling, you can always do profiling of course,
but why copy the efforts others did on it already?

Example - General Statements done such as the one by Robert Klemme
seem to hold true no matter how much profiling one would do anyway:
  "I'd replace that with the general rule to avoid object creation 
because
  that will cover more cases (Array#concat vs. Array#+, String#gsub! vs.
  String#gsub etc.)."


Personally I like such simple truths. :)
