Thanks, that just seems the most flexible approach to me.
I do understand Kiran's advice based on the fact that HLFIR is meant to be closer from Fortran representation than FIR, and maybe I should clarify more the HLFIR vs FIR somewhere. I really think the hlfir.expr type is the corner stone of HLFIR, and if that type cannot be an operand or a result of that operation, it likely better belong to FIR. HLFIR can be seen as "tensor operations for FIR".
