This program performs a memory allocation, so it can throw an out of memory
error. But such exceptions are now meant to be not recoverable, so I think
allocating memory can now be done in nothrow functions too.

But currently with the following code the compiler prints at compile time:
test2.d(1): Error: function test2.foo 'foo' is nothrow yet may throw


nothrow void foo() {
    auto a = new int[5];
}
void main() {}

similar cases:

does no compile
void foo1 () nothrow { auto x = [4]; }

compiles ok
void foo2 () nothrow { int[] x; x ~= 4; }
