What can make scala more popular?

I have an impression that if you try too hard to make super-flexible mechanism then you’ll end up with something costly anyway.

@AMatveev

I think it is possible if move dynamics from a row to a whole dataset.

@tarsa

Show the actual working code and tell where is the redundancy that you would want to avoid.

@AMatveev

// It seams 70 times cheaper than by key access // we can use zero copy approach after all r.set(i,s.get(mapArray(i)))
