Description
=begin
When we have a custom exception class with a custom (({initialize})) method whose arity is not (({1})):
class MyException < StandardError
def initialize x, y
super("Something went wrong with #{x.inspect} because #{y}, blah blah")
end
end
in order to raise it, we have to create a new instance of it explicitly using (({new})), and embed that under (({Kernel#raise})).
raise(MyException.new(:foo, :bar))
This is inconvenient, and does not look object oriented. I propose that there should be (({Exception#raise})), which is public, so that we can do:
MyException.raise(:foo, :bar)
A Ruby implementation may be like this:
class Exception
def self.raise *args; Kernel.send(:raise, *args) end
end
This will disallow us from calling the private method (({Kernel#raise})) (without an explicit receiver) within the context of an (({Exception})) class unless we use (({send})), but I think such use case is rare, and that should not be a problem.
