It does the trick, so I apologize that I've still doubts about the _process_. I guess we should start making cperl-mode.el a "dual life" project soonish - I'll better start a new thread for that. In detail: The point of *this* post was to actually _eliminate_ some fboundp conditionals in cperl-mode.el, so it feels a bit weird to introduce a new one in the same step. I am not particularly concerned about the use of format-prompt, because the calling functions have other issues (cperl-info-on-command is broken anyway, and cperl-perldoc is based on man, which means it fails on Windows and has suboptimal formatting on all platforms). That's outside the scope of this thread, though. But replacement of deprecated / old stuff does occasionally happens across the Emacs repository. This may hit cperl-mode.el at any time, like it did with time-convert and format-prompt. So, every now and then, the Emacs repository will contain a cperl-mode.el which won't work with Emacs 26, until someone notices it and someone prepares another backporting-patch. Or until cperl-mode.el gets a place or procedure where these changes don't hit. -- Cheers, haj
