Special characters in string literals via something analogous to \x3F, \177, \n, \t, \u+1234.
Way to write long string literals split across lines with indentation, without involving format:
TXR Lisp: (foo bar “this is just one \ \ string literal with only single spaces”)
Разве эти две пункта нельзя реализовать с помощью reader-макросов?
