				current token as another, smaller token. For example, ">>=" becomes ">=".

			(*T) ExpectJSXElementChild(token T)
			(*T) ExpectLessThan(isInsideJSXElement bool)
				This parses a single "<" token. If that is the first part of a longer token,

				current token as another, smaller token. For example, "<<=" becomes "<=".
