module Pratt::PrefixParselet

Overview

One of the two interfaces used by the Pratt parser. A PrefixParselet is associated with a token that appears at the beginning of an expression. Its parse() method will be called with the consumed leading token, and the parselet is responsible for parsing anything that comes after that token. This interface is also used for single-token expressions like variables, in which case parse() simply doesn't consume any more tokens.
