--- Comment #13 from Will Wray <wjwray at gmail dot com> ---
Re-reviewing, I notice that the patch I posted in comment #9
now rejects nested empty-brace scalar init:
int i{{}};
which was previously accepted. So we'll need a decision on this too.
Clang rejects with -pedantic-errors or warns otherwise:
pedantic error / warning: too many braces around scalar initializer
MSVC rejects:
error: 'initializing': cannot convert from 'initializer list' to 'int'
note: Too many braces around initializer for 'int'
I reckon that Clang is right to reject under -pedantic, else accept and warn
This Quora post comes to a similar conclusion:

>accepting {{}} for int seems like a harmless language extension.
