Your char may only live in a register in the cpu. In order to cast it to a
single element array, you need to allocate a memory location to store it.

Not quite. While a char is an utf8 code point. char[1] its actually a 
structure like this:

char c = 'a';

struct CharArr1
{
	char* ptr = &c;
	size_t length = 1;
}

You can convert a char to a char[] with this code:

char[] charArr1 = (&c)[0..1];
