The {#syntax#}comptime{#endsyntax#} keyword on a parameter means that the parameter must be known
at compile time.

<p>
Converts a pointer from one address space to another. Depending on the current target and
address spaces, this cast may be a no-op, a complex operation, or illegal. If the cast is
legal, then the resulting pointer points to the same memory location as the pointer operand.
It is always valid to cast a pointer between the same address spaces.
