* libguile/control.h (SCM_F_PROMPT_INLINE, SCM_PROMPT_INLINE_P): Remove; prompts always have "inline" handlers now. * libguile/control.c (scm_c_make_prompt): Remove inline_handler_p arg. * libguile/vm-i-system.c (prompt): * module/language/assembly/decompile-bytecode.scm (decode-load-program): * module/language/assembly/compile-bytecode.scm (write-bytecode): Adapt to prompt changes. * module/language/glil.scm (make-glil-prompt, glil-prompt-inline?): Remove inline? flag. (parse-glil, unparse-glil): * module/language/glil/compile-assembly.scm (glil->assembly): Adapt to <glil-prompt> change. * module/language/tree-il/compile-glil.scm (flatten): Require the handler of a <prompt> to be a lambda-case. * module/language/tree-il/primitives.scm (*primitive-expand-table*): Ensure that the handler of a <prompt> is a lambda-case. * module/language/tree-il/inline.scm (inline!): Simplify a degenerate case: (lambda args (apply (lambda ...) args)) => (lambda ...).
