Just a suggestion for simpler code

Suggested change

	if haskey(kw, :return_bool)
	return_bool = kw[:return_bool]::Bool
	else
	return_bool = false
	end
	kw = filter(p -> p[1] != :return_bool, kw)
	return_bool = get(kw, :return_bool, false)::Bool
	delete!(kw, :return_bool)

[DilumAluthge]

The return_bool = get(kw, :return_bool, false)::Bool part is good.

The delete! throws a MethodError.

This might be better as a @check_reference macro, or something like that?
@test... is kind of tied into the Test architecture?

Not a strong opinion

This is a good change but might need some refactoring work. We've discussed changing the interface to match_reference(x, ref; kw...)::Bool would be a satisfying solution: that people can use normal Tests utilities to do the common work, e.g.,

@test match_reference(line, "this is the reference line")
@test_broken match_reference(line, "this is another line")

[DilumAluthge]

Sure, I can refactor the code out into a match_reference function, and then test_reference would call match_reference under the hood.
