[Lazarus] Strings

Definitely not! ShortString and AnsiStrings (and all other variants of 
string types) are just different ways to work with strings. Using 
ShortStrings you can avoid a lot of problems which you can have with 
AnsiStrings if you don't have the need for strings longer than 255 
characters.

What I would critisize is the use of the generic type "string" at all. 
Mapping this to different types dependend on compiler switches or 
whatever is a can of worms. I would prefer that one of the clear genuine 
string types is used directly. Lots of code is dependend on the string 
type.
