I am trying to follow the rules for unqualified symbol resolution as listed 
at https://clojure.org/reference/evaluation

According to those rules, if my symbol is mapped to a class name in the 
current namespace, then that should override any (hopefully, accidental) 
local bindings of the same symbol. But this does not seem to happen 
reliably in the current version (1.9.0) as shown below. The resolution 
seems to be inconsistent depending on how the symbol is used as you can see 
below.

user=> (clojure-version)

"1.9.0"

user=> (deftype my-t [x])

user.my-t

user=>  ((fn [x] 

(let [my-t 1] 

(println "Now I resolve to the locally bound my-t =" my-t) 

(println "You can even pass me as arguments to functions:" (+ my-t x)) 

(.-x (new my-t "Funnily enough, now I resolve to the class user.my-t")))) 3)

Now I resolve to the locally bound my-t = 1
You can even pass me as arguments to functions: 4
"Funnily enough, now I resolve to the class user.my-t" 


Surely, such a resolution of a symbol alternatively to a local binding and 
a class name is inconsistent, and makes hard to read as well as being a 
potential source of bugs? Am I wrong to expect an error thrown at least 
when evaluating the expression (+ my-t x)?
