[ruby-core:92187]

Description

e.g.

>> def a(b = {}, c: 1); p [b, c]; end; a(a: 1)
Traceback (most recent call last):
        3: from (irb):3
        2: from (irb):3:in `rescue in irb_binding'
        1: from (irb):3:in `a'
ArgumentError (unknown keyword: a)

Prettier version:

def do_something(thing = {}, force: true)
  # doing things
end

do_something({ user: { id: 1 } })
# => ArgumentError (unknown keyword: user)

Tested on ruby-head from ~1 month ago and ruby 2.6.2
