new, delete and nothrow

[Alex Vinokur]

Foo* p = new (nothrow) Foo;

Should we use
operator delete (p, nothrow) ?
Or can we use
delete p; ?

If we use
operator delete (p, nothrow)
how to replace it by operator style?

delete (nothrow) p; // Compiler rejects that

not like that, you must call it in a normal function call way

if Foo has a delete operator like this
void operator delete(void *, std::nothrow_t)

Foo * p = new (std::nothrow) Foo;
p->operator delete(p, std::nothrow);
