[New-bugs-announce] [issue44502] bla in cpython/Lib/test/test_sys_settrace.py

[zcpara]

New submission from zcpara <zhangchaospecial at gmail.com>:

In cpython/Lib/test/test_sys_settrace.py, there is a function:
1 def no_pop_blocks():
2    y = 1
3    while not y:
4        bla
5    x = 1

what does bla mean? bla is not defined anywhere. But the function can pass the compilation. bla is treated as a global name in symtable during compilation. Why does python allow this statement (line 4)? Will line 4 be deleted in the future? Or be replaced with pass?
