The function `bar' is responsible for asking the user for some value and passing that value to the guts of `foo'. Now I want to call `foo' in the Mafia-mode;-), i.e., it should ask no further questions. What do I do? AFAIU, `cl-flet' won't help, since it is lexical. The best I can think of is to temporarily advice `bar' with :override - but then, instead of a `let'-like, local construct, I have to explicitly add and then remove the advice, right? Any other ideas? TIA, -- Marcin Borkowski http://octd.wmi.amu.edu.pl/en/Marcin_Borkowski Faculty of Mathematics and Computer Science Adam Mickiewicz University
