Referring to array element by descriptive name

Thank you for all your answers. I was concerned because I'm 
dealing with a small function that is called many times and where 
the bulk of the calculations in the simulation takes place. So 
even 5% performance difference would be significant for me. But 
it is good to know that compilers are smart enough to optimize 
this.
