How would I do (filterv #(-> % :id nil?) foo) with specter? Or would I not?

@mbertheau two approaches:

(select [ALL #(-> % :id nil?)] foo)

(setval [ALL #(-> % :id some?)] NONE foo)

the first always returns a vector, the second maintains the type of whatever foo is

@nathanmarz I'm just starting out with specter - thanks for helping me up the initial learning curve!

sure, no problem
