(alias 'sn (create-ns 'some-namespace))
::sn/foo ;=> :some-namespace/foo

How to avoid this warning? Note: there is no file some_namespace.clj so I can't require it.

(alias 'sn (create-ns 'some-namespace))
::sn/foo ;; false positive
sn/foo ;; works

ah no, I was fooled, clj-kondo only reports the first occurrence of the unresolved namespace

this does seem to work:

(alias 'sn 'foo #_(create-ns 'some-namespace))
::sn/foo

this could be improved though, so issue still welcome

for now you could write:

(create-ns 'foo)
(alias 'sn 'foo)
::sn/foo

Ok, I will post an issue. Thx for workaround.

Are there any common causes for unsupported binding form errors to occur in code generated by hooks?

@suskeyhose it's usually best to just print the node to see what it looks like

Like right now I'm just putting a symbol into a vector used in an argument list to a fn

Yeah, I'm printing the node, and it looks fine

<list: (fn [] (fn [field value second item timestamp] [field value second item timestamp] [second field] {:type :http :method :get :body {:field field :value value :timestamp timestam}} ()))>

This is what's being generated

And it's saying timestamp is an unsupported binding form.

Oh, I think I might know

I forgot to turn the symbol into a token node

right, that's a common thing

yup, that was it
