We are not catching SyntaxError: unqualified exec is not allowed in function 'xxx' it is a nested function

Notice this when trying one of our existing tests. (I attached it in case the file changed). Sorry for no simpler repro.

D:\merlin2\Main\Languages\IronPython\Tests > cpy test_methoddispatch.py
File "test_methoddispatch.py", line 909
exec line
SyntaxError: unqualified exec is not allowed in function 'testfunctionhelper' it is a nested function

Here's repro code:

def a():
    def b():
        exec('print("A")')
        return None

Under CPython 2.7 it fails with:

SyntaxError: unqualified exec is not allowed in function 'b' because it is a nested function

Here's a variation:

def a():
    def b():
        return None
    exec('print("A")')

This one fails (under CPython 2.7) with:

SyntaxError: unqualified exec is not allowed in function 'a' because it contains a nested function with free variables

Both appear to be acceptable with CPython 3.5 or IronPython. My question is then, does IronPython work properly? I assume CPython 2.7 has those restrictions for a reason...
