Suggestion: Add section or clarification about datatypes in variable names

[jezeke]

One major contributor of code smell (in my opinion) is code that superfluously includes the type of the thing in its name. (e.g. List itemList, or CREATE TABLE itemTable instead of just items). This goes hand-in-hand with the "avoid context-duplication" rule too.

One edge-case to consider is date type variables- whereby you may have item.dateAdded, and simply removing the type from the name leaves you with item.added, which is very unclear (sounds more like a boolean flag set if the item has been added). My personal preference is to follow the form of At. So, dateAdded would be addedAt. This defies the A/HC/LC pattern somewhat however, so take it as you will.
