Bug #14909: Method call with object that has to_hash method crashes (method with splat and keyword arguments)
https://bugs.ruby-lang.org/issues/14909
* Author: johannes_luedke (Johannes Ldke)
* Status: Open
* Priority: Normal
* Assignee:
* Target version:
* ruby -v: ruby 2.4.1p111 (2017-03-22 revision 58053) [x86_64-darwin17]
* Backport: 2.3: UNKNOWN, 2.4: UNKNOWN, 2.5: UNKNOWN
----------------------------------------
In a method with a splat method argument followed by a keyword argument, it leads to an `ArgumentError` when calling the method with an object that reacts to `to_hash`
~~~ruby
def my_func(*objects, error_code: 400)
objects.inspect
end
class Test
def to_hash
# an example hash
{ to_hash_key: "to_hash" }
end
end
my_func(Test.new)
~~~
Observed result: an exception is raised: `in my_func: unknown keyword: to_hash_key (ArgumentError)`
Expected result: `[#<Test:0x007fc8c9825318>]` is returned by the `my_func` call
It should behave the same when calling with objects that have a `to_hash` method and objects that don't, shouldn't it?
