>>>I do that, but not for readability. I do it because each time I don't, there comes a case when I need that value elsewhere in the code, and I don't want to call alen() multiple times.

The code may later redimension the array, and alen() would give a different result. In that case, I prefer having another variable to hold the new array size, so I know which is which without misreading the code.

On my test ALEN() is a few microseconds faster that retrieving a value of a variable.
