My thought was to explain that we explicitly declared the list in the right order (meaning the list keeps its order from init).
It might be too explicit, if so I'll change it back :)

Merge with the line about באגים, so it would sound more natural.

המספור של התא הראשון הוא 0, ולא 1. יש לכך סיבות טובות, אבל פעמים רבות זה ירגיש לא טבעי.

בלבול של המתכנת בעקבות ההתנהגות עלול לגרום ל<dfn>באגים<dfn>, קטעי קוד שמתנהגים אחרת משציפה המתכנת.
