libpython-clj2.metadata/pyarglists is not returning 'defaults'

[behrica]

When using fn libpython-clj2.metadata/pyarglists the deafults are not shown, see below.
py-fn-argspec seems to find them, but then they get eaten up, to me on this line:

libpython-clj/src/libpython_clj2/metadata.clj

Line 150 in 97dff5c

(map (fn [[k v]] [(symbol k) (keyword k)]))

[(symbol k) (keyword k)] seems wrong, should be: [(symbol k) (keyword v)]
but (keyword x) returns for example "nil" on true, so defaults true are lost.

I think [(symbol k) v] should work, but not sure if for all cases.

(libpython-clj2.python/from-import os fwalk)
(-> 
 (libpython-clj2.metadata/py-fn-argspec fwalk)
 (libpython-clj2.metadata/pyarglists))

;;=> [[& [{top :top, topdown :topdown, onerror :onerror, follow_symlinks :follow_symlinks, dir_fd :dir_fd}]]
;;    [& [{top :top, topdown :topdown, follow_symlinks :follow_symlinks, dir_fd :dir_fd}]]
;;    [& [{top :top, follow_symlinks :follow_symlinks, dir_fd :dir_fd}]]
;;    [& [{follow_symlinks :follow_symlinks, dir_fd :dir_fd}]]]

in python:

>>> import os
>>> help (os.fwalk)
fwalk (top='.', topdown=True, onerror=None, *, follow_symlinks=False, dir_fd=None)

fixing this is more complex, defaults can be anything:

(py/from-import numpy.random randint)
(->
 (libpython-clj2.metadata/py-fn-argspec randint))

;;=> {:args ["self" "low" "high" "size" "dtype"],
;;    :varargs nil,
;;    :varkw nil,
;;    :defaults
;;    [nil nil {:type :type, :value #object[tech.v3.datatype.ffi.Pointer 0x7c920c7f "{:address 0x00007FFA92BD0E00 }"]}],
;;    :kwonlyargs [],
;;    :kwonlydefaults nil,
;;    :annotations {}}

I solved this differently, staying on python side and taking the "str" of each parameter from 'inspect'

(py/from-import numpy.random randint)
(require 'libpython-clj2.require)
(libpython-clj2.require/import-python)
(->
 ((py/get-attr inspect "getfullargspec") randint)
 (py/get-attr "defaults")
 (py/get-item 2)
 (builtins/str)
 str)
;;=> "<class 'int'>"
