type Substring[+S <: String, +IBeg <: Int, +IEnd <: Int] <: String

Substring of a String singleton type, with a singleton type begin inclusive index IBeg, and a singleton type exclusive end index IEnd. The substring begins at the specified IBeg and extends to the character at index IEnd - 1. Thus the length of the substring is IEnd-IBeg.
