  I'm aware, that at my point of education there's no sense in optimizing code
to squeeze from it every millisecond, but Project Euler gave me habit to
compare time consumption of script every time I make serious change in it.

  Your tune-ups made this script (mostly check() I guess) about 20% faster. So
it's not only 'more readable' profit. :-)
