Just out of curiosity: what limitations of Ruby 1.9.3 is critical in your case?

Not to start a flame war, but according to my experience, Ruby 1.9 is already quite good, later versions of Ruby only introduce minor syntax & semantic changes, which is trivial to work around. This is nothing like the big differences between 1.8 and 1.9

I agree with package availability problem of mruby, tho.

Nothing is critical, I'm just so used to writing Ruby 2.3 at this point that 1.9 isn't as enjoyable. I wish it were better, I'm not saying it's bad.
