JFYI: we also have mallocarray(), which is nice when one of the parameters is untrusted. A naive multiplication can overflow and result in allocating less memory than expected, which can result in security vulnerabilities in the worst case. mallocarray() will panic in this case instead.

I don't think it matters here, just thought I'd mention it.
