Hi,

The changes to DMD from the previous week made some druntime unittests fail. Specifically, some of those in core.lifetime, because the existing _d_arrayctor implementation could not be @nogc.

I spent this week fixing the above issue by removing the call to enforceRawArraysConformable from _d_arrayctor, and performing its checks "manually". enforceRawArraysConformable prevented _d_arrayctor from becoming @nogc because it created its error messages by string concatenation, which is not @nogc.

The PR that should fix these issues is here.

I haven't been able to work on _d_arrayappendT and _d_arrayappendcTX, but I plan to catch up next week.

Thanks,
Teodor
