After the last Emacs upgrade to 26.1, the M-s key bind from paredit-mode is replaced by `Next element matching (regexp)` command in the slime repl buffer. Sorry for the silly question, but how to get M-s mapped to paredit-splice-sexp again? In a lisp file buffer it is working as expected.

(push (lambda () (local-set-key (kbd “M-s”) ‘paredit-splice-sexp)) slime-repl-mode-hook)

or more emacsy: (add-hook ‘slime-repl-mode-hook (lambda () (local-set-key (kbd “M-s”) ‘paredit-splice-sexp)))

Also to consider: there’s probably a keymap for the silme-repl-mode, you could modify it directly.
