You can write an essay about it in the J wiki.
Another one:
The foreign m!:n would be slightly more concise and easier
to use if !: were an adverb with the encoding being (n+100*m)
or perhaps (n+10*m). Or perhaps use : and word formation
instead of !: and adv/conj:
old new
3!:0 30!: or 30:
3!:1 31!: or 31:
3!:2 32!: or 32:
Another one:
Since the dyad u/ is just u"(lu,_) , perhaps it should be
assigned a different, more useful meaning. e.g.
x u/ y
x if 0=#y
(0{y) u (1{y) u ... u (_2{y) u (_1{y) u x if 0<#y
That is, > u&.>/ (<"_1 y),<x if 0<#y .
Another one:
Array semantics but "LISP syntax". e.g.
((" * 1) (i.2 3) 3 4 5) instead of (i.2 3)*"1 (3 4 5)
etc. Once you start this game the possibilities
are endless.
