Hi @gesarpis, thanks for opening this new MR. Were these new lines presented in one of the Charm WG meetings?
Resolved by Gediminas SarpisHi @cacochat, no not really, I need them for my next position that I start in a few months so the deadline pushed me to write them asap. I have made Tomasso and Federico aware of my plans just before the New Year.
