Looks like std.stdio isn't marked with @nogc all the way either.

So for now the temporary solution would be to use std.c.stdio.
Get the file size, malloc a buffer large enough for it[1],
use std.c.stdio.read to fill it, assign it to a char[] slice
and std.utf.decode to consume the text...

Oh wait, decode isn't @nogc either. FFS, what now?


[1] I assume the file is small, otherwise there would be an extra step
involved where after nearing the end of the buffer you move the rest
of the data to the front, read new data after it, and continue decoding.
