[std.setops] setInterospection overly constrained to require number of sets to known at compile time

[crazymonkyyy]

I have introspectionpacket[][] which look like:

[[introspectionpacket(0, "x"), introspectionpacket(4, "y")], 
[introspectionpacket(0, "x"), introspectionpacket(4, "y"), introspectionpacket(8, "z")]]

I want the output: [introspectionpacket(0, "x"), introspectionpacket(4, "y")]

as written the first 2 ways that come to mind on how to call set introspection fails

throwing at ai with prompt "dlang, std setintrospection sux, I need it to handle int[][]; investigate" seems to have worked producing these artifacts:

I disagree with its solution, but do as you will
