So, it's actually there! I may have suspected it...

Hmmm, this works in what I would call a complementary way. Of course I suppose 
it's enough to save the Perl script to disk. I wonder if there's any way to 
make it work by selecting it from a buffer instead. (Which, for maximum 
reliability would include to temporarily save to disk, IMHO, as opposed to 
passing it to the perl executable through STDIN...)

PS: I just tried perl_exec, which of course works like a charm, and I feel like 
an idiot for not having known about it for years! Anyway... I don't have a 
keybinding for it: of course I can set it up FOR ME and it would make some 
sense since after all I *only* (well, mostly, but that's another story) program 
in Perl. But that brings us to another problem: namely, that of orthogonality 
between main editing modes (i.e. keybindings) and language-specific modes. I 
believe the former ones should provide an "introductory keybinding" upon which 
the latter ones could form composed ones. For example, I see ^J is not taken by 
the ide mode I use. Then the perl mode may use it abstractly (i.e. asking it to 
some function which I don't know) to form ^J-e, ^J-c and assign them to 
perl_exec, perl_check and so on. And similarly other modes. Does it make sense? 
If so, then I'm asking you the permission to forward this very mail to the JED 
ML. I would like to know what the other guys think of it.
