any caveats or are they drop-in replacements for every corner case?

Ben Sless11:12:39

@U11SJ6Q0K I think they are a drop in replacement but I haven't checked every corner case yet. I did try to not make any assumptions regarding usage. The only caveat I can think of now is that the * versions generate a lot of inlined code, so you could in extreme cases get a compiler exception for method size, especially if mixed with other code generation libraries

I was thinking that could these be sometime included into core, in the fullness of time

Ben Sless13:12:49

I would hope so. Especially the solution using reduce for select-keys has relatively good performance vs. a small amount of changes.
