Doesn’t this incur a runtime bounds check? Also does this work 
with non-void slices?

No, it would allocate new stack memory or use a new register. 
You’ll assign the expression to something anyway, so it’s like if 
you declared a default initialised variable and partially 
overwrote it. I’ve actually needed this pattern quite a lot when 
interacting with C and often I just have to cast to `ubyte[]` and 
write all the lengths manually. Looks ugly.
