Performance #3
Description
I am speculating on how much does it takes to obtain a new translator for each route handler, it they can be safely created once per language and then shared amongst handlers, and also if it's possible to pass a &T instead of T in the templates execution contexts. Could be nice to have the package assemble a map of translator for each language specified in POGO.toml. Anyway, I'll comment more on performance after some profiling.
