From [Go Your Own Way (Part Two: The
Heap)](https://dlang.org/blog/2017/09/25/go-your-own-way-part-two-the-heap/):
`import core.stdc.stdlib;`
`// Allocate a block of untyped bytes that can be managed`
`// as a slice.`
`void[] allocate(size_t size)`
`{`
`// malloc(0) is implementation defined (might return
null `
`// or an address), but is almost certainly not what we
want.`
`assert(size != 0);`
`void* ptr = malloc(size);`
`if(!ptr) assert(0, "Out of memory!");`
`// Return a slice of the pointer so that the address is
coupled`
`// with the size of the memory block.`
`return ptr[0 .. size];`
}
`T[] allocArray(T)(size_t count) `
`{ `
` // Make sure to account for the size of the`
` // array element type!`
` return cast(T[])allocate(T.sizeof * count); `
`}`
What is the equivalent for higher dimensional arrays?
