cl-return-fromcl-return-from is an autoloaded Lisp macro in `
cl-macs.el'. (cl-return-from NAME &optional RESULT) Return from the block named NAME. This jumps out to the innermost enclosing `(cl-block NAME ...)' form, returning RESULT from that form (or nil if RESULT is omitted). This is compatible with Common Lisp, but note that `defun' and `defmacro' do not create implicit blocks as they do in Common Lisp.
