Description
The following behavior for dig
looks very weird to me:
o=Object.new
def o.dig(**kw) p [kw] end
o.dig(x:1)
#no warning
#[{:x=>1}]
[o].dig(0, x:1)
#warning: Using the last argument as keyword parameters is deprecated
#[{:x=>1}]
o=Object.new
def o.dig(a, **kw) p [a,kw] end
o.dig(x:1)
#warning: Passing the keyword argument as the last hash parameter is deprecated
#[{:x=>1}, {}]
[o].dig(0, x:1)
#no warning
#[{:x=>1}, {}]
So the keywords are interpreted as a positional hash, resulting in the opposite of the behavior I would expect.
This would be easy to fix by changing rb_obj_dig
to use
return rb_check_funcall_with_hook_kw(obj, id_dig, argc, argv,
no_dig_method, obj,
RB_PASS_CALLED_KEYWORDS);
What this just an oversight? I can't think of a rationale for the current behavior.
