This has to be recent then, both the above snippets do not produce that
deprecation warning on Nim 0.18.0 at play.nim-lang.org in the presence of
pragma experimental, while producing exactly that warning without experimental.
I'll check it again on devel when I get back to my machine. It seems
I do use {.experimental.}. The communicate is precisely: "Warning: overloaded
'.' and '()' operators are now .experimental; () is deprecated [Deprecated]"
Did you add the {.experimental.} pragma? That should remove the deprecation
warning, as that warning happens because () is experimental.
Cool! I didn't see it coming, () operator. Last time I asked about it, there
was no proposal of it yet, if my memory serves me well.
: int): int = c.val * i
# Make the thing exponentiable.
proc `^`(c: Callable; i: int): int = c.val ^ i
let c = Callable(val: 1)
echo c ^ 2 == 1.c ^ 2 # true!
You could probably object-ify any given function to behave this way using a
macro.
I would like to have a function behaving like an object, so I could overload an
operator on that function. I need the following to be true:
assert 1.fun ^ 2 == fun ^ 2
I know I could use fun() with a default argument but that's that syntax isn't
acceptable in this context
