Note that if a file is being parsed and not a string the behaviour is this:
╰─ cat -e t.py
x = 1 | 2 | $
╰─ ./python.exe t.py
File "/Users/lysnikolaou/repos/cpython/t.py", line 1
x = 1 | 2 |
^
SyntaxError: invalid syntax
╰─ ./python.exe -X oldparser t.py
File "/Users/lysnikolaou/repos/cpython/t.py", line 1
x = 1 | 2 |
^
SyntaxError: invalid syntax
Would we want to also change this? If not, then I guess that we should as closely as possible match this behaviour with strings as well, which means not clipping.
