SyntaxError of global declaration don't stop program

[HyeockJinKim]

a = 3
global a
print(a)

b = 2 + 5
print(b)

This code generate syntax error, but gpython doesn't stop program

Expected Result

Hyeockz:bin hyeockjinkim$ python3 g.py 
  File "g.py", line 2
    global a
SyntaxError: name 'a' is assigned to before global declaration

Actual Result

2019/09/09 00:08:36 name 'a' is assigned to before global declaration

SyntaxError in python3 is Error, not warning. So I think it should be modified.

If this issue is valid, can I take it?

Interesting, that behaviour has changed from python3.4 to python3.7

Gpython is following python3.4 for the moment so it should be generating a SyntaxWarning

$ /opt/python3.4/bin/python3.4 /tmp/z.py 
/tmp/z.py:2: SyntaxWarning: name 'a' is assigned to before global declaration
  global a
3
7

$ python3.7 /tmp/z.py 
  File "/tmp/z.py", line 2
    global a
    ^
SyntaxError: name 'a' is assigned to before global declaration

If this issue is valid, can I take it?

Happy to have help, so yes!

FYI, @HyeockJinKim is a mentee of OSS program named Contributhon of Korea government.
It's a similar program like GSoC.
(A few months ago I posted a mailing list about this program )
I am mentoring @HyeockJinKim for a month.

There are also some people(4-5) who want to contribute gpython project for the first time.
so they need our help too.

And I am going to assign issues to them with Contributhon 2019tag. (It is the program name)
