:57159596 k9 uses expressions with dicts(and tables): d@e e.g.
(`a`b!1 2) :a+b returns 3

@ngn this is mean: Object.defineProperty(x.prototype,'n',{get:function(){return this.length}})

@ktye ouch. i can't believe k6 and k9 were designed by the same person

how does this work? ((:a+b;:a*b)!1 2) :a+b

@ktye got tired of typing .length :D

@coltim thanks, it's a type error now

that fixes _\dict too

@ngn dict@expr evaluates the expression within the "environment" of the dict. what's wrong about that? it's used with tables for computed columns.

@ktye it steps on the toes of dict indexing. the nilad could be a key in the dict.

in other words, the nilad is not treated as a first-class object anymore. that's bad.

@ngn now i understand. no problem: ((:a+b;:a*b)!1 2) :a+b returns 1
