If my caller needs a List, that's a single easy method call away - I don't need to make that decision for them, and that makes my cod...
Scanner vs. BufferedReader
...ion of read() or readLine() could
cause bytes to be read from the file, converted into characters, and

appreciably if a Reader is warped in a BufferedReader.
BufferedReader is synchronized, so read operations on a Buf...
Are there strongly-typed collections in Objective-C?

@interface GenericsTest<__covariant T> : NSObject
