what about the following :
b = "joint"
1000.times()
{
  a = ls(:type => b)
}
It would be more like standard Ruby and will certainly will be simpler
to do.

And to be able to call the MEL methods inside Ruby, you could do
something like that :
module Kernel
    def method_missing( symbol, *args )
    # call the corresponding MEL function
    end
end

And if you do not want to 'pollute' the Kernel module, juste create a
new module called MEL for example with method_missing. You would just
have to call MEL.ls(:type => b)

PS : I am not very good in Ruby and I am replying without having the
time to check anything on a Ruby interpreter. I just hope it will be
of some use :-).
