New submission from Batuhan Taskaya <isidenti...@gmail.com>:
(.venv) (Python 3.10.0a0) [ 1:11ÖS ] [ isidentical@x200:~ ]
$ cat t.py
import x
a = 1
print(x)
(.venv) (Python 3.10.0a0) [ 1:11ÖS ] [ isidentical@x200:~ ]
$ python -m symtable t.py
<symbol '_symtable'> True False
<symbol 'USE'> True False
<symbol 'DEF_GLOBAL'> True False
<symbol 'DEF_NONLOCAL'> True False
<symbol 'DEF_LOCAL'> True False
...
It can clearly seen that the initial argument [t.py] is completely ignored, and
this script prints out the symtable.py itself. This is because the script uses
argv[0] (itself) instead of argv[1] (the first argument). I also find this
output quite poor since we don't know what these boolean values are;
<symbol 'DEF_LOCAL'> True False
The fix I had in my mind is printing all properties instead of 2 boolean values
$ ./cpython/cpython/python -m symtable t.py
<symbol 'x'> ==> {'local', 'imported', 'referenced'}
<symbol 'a'> ==> {'local', 'assigned'}
<symbol 'print'> ==> {'referenced', 'global'}
