--- Comment #3 from Steven Schveighoffer <schveiguy at yahoo.com> ---
This is one of those "magic" calls from the compiler to the runtime. I agree it
can be replaced with a template, and then the linker error will be replaced
with a compile time error (or maybe one can provide a betterC runtime that
works without druntime?)

The TypeInfo is how the old-time runtime functions communicated the type. There
is slow but steady progress to replace these calls with template calls,
allowing the runtime more control over what happens.
