forgive the neophyte inquiriry, I'm attempting to emulate

(update-in {} [:a :b :c] (fnil concat [])  [1 2 3])

for practice I'm just trying it on one nested value

(setval [:a NIL->VECTOR END] [1 2 3] {})

ah I see... so the above is working it's when I'm dealing with a vector-as-a-key that it's an issue

(setval [:a (must [:b :c]) NIL->VECTOR END] [1 2 3] {:a {}})

current working work around... not pretty but it works

@goomba I think you want (must :b :c) or (apply must [:b :c])

hmm well no luck so far but my guess is in general I'm still not a high enough level specter yet

you don't happen to know @nathanmarz of any open source projects that are making good use of your library do you? Would love to see more examples

I'm always getting so close to what I want to do but just always missing a piece

for instance, navigating to the maximum of a set of elements

(select [MAP-VALS :index MAX] {:a {:index 0} :b {:index 1}})

of course that's simple enough to do with other functions but just trying to learn to think in specter haha

@goomba I don't really keep track of how specter is used by other open source projects

you can try doing a github search

no problemo... working through some of your examples

MAX would have to be done with defnav
