Not a paper, but one of my favorite talks https://www.youtube.com/watch?v=_ahvzDzKdB0&t=642s https://www.youtube.com/watch?v=_ahvzDzKdB0&t=642s Growing a Language by Guy Steele (co-inventory of Scheme). Brilliant speech about how to grow languages and why it's necessary. Languages that can be grown by the programmer, like Lisp or Smalltalk are better than languages that fixed like most others, this is why.
