Re: [Patch] Fortran: Fix assumed-size to assumed-rank passing [PR94070]

Hi Tobias,

let me first reach for my brown bag...

It was probably too late, and I could no longer distinguish
"assumed-size" from "assumed-rank", and likely some more...

... which lead to my complete confusion and loss of focus.

Of course you are right.  Sorry for that.  Will now put that bag on...
