FrozenError.new ignores receiver:
Other exception classes with receiver accept recevier as keyword argument of new.
But FrozenError.new accept as positional argument.
I think keyword argument is better consistency.
% git grep 'receiver[:=]' ../error.c ../error.c: * FrozenError.new(msg=nil, receiver=nil) -> name_error ../error.c: * NameError.new(msg=nil, name=nil, receiver: nil) -> name_error ../error.c: * [1, 2, 3].method(:rject) # NameError with name "rject" and receiver: Array ../error.c: * [1, 2, 3].singleton_method(:rject) # NameError with name "rject" and receiver: [1, 2, 3] ../error.c: * NoMethodError.new(msg=nil, name=nil, args=nil, private=false, receiver: nil) -> no_method_error ../error.c: * KeyError.new(message=nil, receiver: nil, key: nil) -> key_error

Whether to use a positional argument or a keyword argument was discussed in #15751. I don't have a strong feelings either way (one of the patches I added in #15751 supported keyword arguments), and I don't think Eregon (Benoit Daloze) or nobu (Nobuyoshi Nakada) had strong feelings either. If you are strongly in favor of switching to a keyword argument, please commit the change. I'll probably not be in a position to commit anything until December 20.
