• Ruby Gotcha: Extending non-existent class displays confusing error message

class Foo < DontExist
end

describe Foo
it “works” do
Foo.new
end
end

this raises:

uninitialized constant Foo (NameError)

very confusing to say the least. I would have expected the NameError to show that DontExist didn’t exist.
