--- The current lexical state value.
-- @function State
-- @treturn int

--- Set the style of the current token to the current state and then change the state to the argument.
-- @function SetState

--- Combination of moving forward and setting the state.
-- Useful when the current character is a token terminator like " for a string.
-- @function ForwardSetState

--- Change the current state so that the state of the current token will be set to the argument.
-- @function ChangeState

-- @tparam int line
-- @tparam int state

--- Start of the range to be lexed.
-- @tparam[readonly] int startPos
