ruby 3.1.2p20 (2022-04-12 revision 4491bb740a) [x86_64-linux]
Backport:

Description

The two patterns in the code below behave differently:

def f(obj)
  case obj
  in foo:
    0
    true
  in "bar":
    0
    true
  else
    false
  end
end

p f({ foo: 42 }) # => true
p f({ bar: 42 }) # => false

which does not seem an intended behavior.
