We already these issues with 'co_name', though. These cases can be
treated the same as they are for 'co_name':
'<listcomp>'
>>> compile('[i for i in [1, 2]]', '<foo>', 'exec').co_consts[0].co_qualname
'<listcomp>'
>>> compile('class T: pass', '<foo>', 'exec').co_consts[0].co_qualname
'T'
>>> compile('class T: pass', '<foo>', 'exec').co_consts[0].co_name
'T'
>>> compile('a = 12', '<foo>', 'exec').co_name
'<module>'
>>> compile('a = 12', '<foo>', 'exec').co_qualname
'<module>'
>>> compile('lambda x: x', '<foo>', 'exec').co_consts[0].co_qualname
'<lambda>'
>>> compile('lambda x: x', '<foo>', 'exec').co_consts[0].co_name
'<lambda>'
