Fixes #2445
This seems to help with the type inference regression in Julia v1.11. #2445 should be fixed anyway in v1.11.3, but never hurts to help the type inference machinery, let the compiler unroll the loop if it feels like it.
Also made the same change in
initialstep
, for consistency, and to neatly ensure thatstates
is always a tuple. Also, in the process, removed some initialisation of the varinfo ininitialstep
, that was repeating work done in https://github.com/TuringLang/DynamicPPL.jl/blob/e673b69210e85b60199f2ccd8165226cb03cf040/src/sampler.jl#L113.
