Also vibe.http.rest and vibe.http.form create really lot of 
template instances because of heavy usage of reflection + code 
generation. This is one of domains though that can potentially 
improve a lot by better compiler implementation,

That should be possible and relatively simple (because of CTFE 
nature a lot of code can be reused). It may considerably impact 
Diet performance but I can see desire for that in development 
mode as project size increases. As usual, it is mostly matter of 
manpower - vibe.d has only one persistent contributor right now 
and probably 5-8 guys doing occasional pull request, definitely 
not enough for project of that scale.
