Can we have more /* ... */ comments as well. And more than one comment as well? something like:

inst(OP, (-- value)) {
    // Comment is ok
	value = ...
}

inst(OP, (-- value)) {
    /* comment is ok */
	value = ...
}

inst(OP, (-- value)) {
    /* 
     comment is ok 
	*/
	value = ...
}

inst(OP, (-- value)) {
	// comment
	// comment
	value = ...
}

inst(OP, (-- value)) {
	// comment
	value = ...
	// comment
}

(I don't know which comments are actually accepted). The output being always the same, you can parametrize the test as follows:

output = ... 
line = "value = PyStackRef_FromPyObjectNew(GETITEM(FRAME_CO_CONSTS, oparg));"
for src in [
	("//", line),
	("// comment", line),
	("/* comment */", line),
    ...
]:
	lines = textwrap.indent('\n'.join(src), " " * 4)
	input = f"inst(OP, (-- value)) {{\n{lines}\n}}"
	with self.subTest(src=src):
		self.run_cases_test(input, output)
