some languages need a lot of discretionaries for proper hyphenation, and allowing to specify whole-word exceptions with arbitary discretionaries is already a good step forward, but i wonder if you plan to extend the \patterns mechanism to support arbitrary discretionaries too? For sure. Feel free to propose a syntax ;-)

Of course, while we are at it, we want \patterns{a23b} to have the normal meaning of "2", but delivering a penalty corresponding to 70 when we have specified \hyphenpenalties 5 10 30 40 70 20 (similar to the widowpenalties multiplicity). That allows specifying breakpoints with various priorities (good and bad ones).

I am having a hard time parsing this. How does the "3" relate to the value "70"? Also, how do you propose to create such pattern files? Best wishes, Taco
