Yeah I've discovered to my great surprise the other day that 
opaque pointers are not enabled yet but optionally supported. By 
coincidence at the same time I was just celebrating the 
transition to opaque pointers of [another 
compiler](https://gitlab.com/styx-lang/styx/-/releases/v0.10.0)... For LDC this is more complicated because (I believe) the LLVM IR is generated from another intermediate IR so the relationship with the original AST is not so obvious.

Anyway, no matter if the reg was caused by the initial support 
for opque ptrs, LLVM GEPs were generally more simple with typed 
pointers.
