Serhiy Storchaka added the comment:
I have concerns about following cases.
* f-string containing multiple equivalent subexpressions:
f'{x} {x}'
or
f'''
{x}
{x}
'''
* f-string containing escaped newlines:
f'''\
\
{x}\
\
'''
The tests look slightly verbose and fragile to me. If once the parser will
produce more efficient tree (see issue26415), the tests may fail. Needed more
tests (for cases mentioned above), and adding them will add more verbose code.
Maybe just find the child (or several children) of specific type and check
lineno and col_offset only for it and few its children? If this will make the
tests simpler. But if tests can't be made simpler, we should live with this.
