I think there are. In particular if you're initializing a struct by
members which doesn't have a constructor. For instance, when I
recently upgraded layers id from a uint64_t to a struct, I had to use
{} in initializer lists instead of () because I didn't add a
constructor to the struct. Here's a simple example:
struct Foo {
int x;
};
struct Bar {
Bar()
: mFoo(0) // <-- this fails, but {} will work
{
}
Foo mFoo;
};
