Is there a way with specter to transform the first element matching a predicate?

@exupero: I had this working for me:

(spec/transform [:new-entity :columns spec/ALL #(= (:id %) id)] #(assoc % key val) @state)``

I guess if you switch ALL by FIRST it will only transform the first met one

Using FIRST pred seems to get the first item in the sequence, then filter it on whether it satisfies the predicate.

Essentially I want ALL pred FIRST.

But that gives the error Vector’s key for assoc must be a number.
