It is lowered to:

In all other languages with string interpolation that I'm
familiar with, `a` is not passed to the `i` parameter.

To be fair, none of those languages care about an extra string
allocation.
But to be fair again, Adam/Steven's proposal can avoid the memory
allocation while also not passing i implicitly, at the cost of
not matching to the string type.
But to be thrice fair, Adam/Steven's proposal would work with the
minor extension `f(i"hello $a".format)`/`f(i"hello
$a".to!string)`, in keeping with the trend of GC use requiring
explicit opt-in.
