This week I have checked on Rainer's PR [1], helping a bit with some failing tests. The PR now seems to be pretty much ready to be merged.

I have also created benchmarks for the templatized _d_arrayliteralTX[2] and AA[3] hooks. The results for [2] ran with dmd were pretty good, showing both performance improvements and size reductions in the libdruntime/libphobos. I am going to run [3] as well, but might wait until the PR is merged. In any case, there won't be any conclusive results until the modifications are integrated into ldc/gdc and tested with those compilers.

Excited to see the progress on the hook templatisation, going to make it easier to maintain custom runtimes.
