Hello,

Something changed in dmd? Should I fix my code or wait for dmd release, not 2.107-beta.1 ?

There seems to have been some compiler change in dmd 2.101, released Nov 2022. Tests successfully complete with 2.100.2 but fail with 2.101.2.

$ mkdir -p ~/dlang && wget https://dlang.org/install.sh -O ~/dlang/install.sh
$ ~/dlang/install.sh update
$ ~/dlang/install.sh dmd-2.100.2
$ ~/dlang/install.sh dmd-2.101.2

$ dub test --compiler=$HOME/dlang/dmd-2.100.2/linux/bin64/dmd 2>&1 | grep Error
