I understand that this is dictionary compliant: "In general, each cell of x is applied to the entire of y . Thus x u/ y is equivalent to x u"(lu,_) y where lu is the left rank of u ." +"_1 b.0 _ _ _ So u"_1/ -: u"_ _ . Wouldn’t it be better though if u"_1/ -: u"_1 _ , or if (u”_1 b.0) -: _1 _1 _1 (or any other negative rank)? I ran into this while trying to use ,"_1/ , which I can replace by >@{@,&< , but I still find this strange.
