Hello all.
I have a following deftype:
(deftype NDArray
[^objects data
^long ndims
^longs shape
^longs strides])
(
https://github.com/si14/matrix-api/blob/70b376f58ec3846df6622b971001c3ade32d0725/src/main/clojure/clojure/core/matrix/impl/ndarray.clj#L30
)
Then, when I use "data" field in various contexts like aget/aset, Clojure
warns me about reflection (and rightfully so). It's not a problem with
primitive arrays because we can use (longs …) and similar functions to make
cast explicitly, but there is no (objects …). With some googling I've found
a following solution:
(let […
#^"[Ljava.lang.Object;" data (.data m)
…]
(aset data idx v))))

)
But it's really really ugly. Is there a way to make it better?
