Hey Ty,
Why are you worried about increasing compiled binary size? Templated
types are only generated if you use them (i.e. a vector of players,
rooms, etc). If you hand-roll a version of vector's to handle each
datatype (i.e. a vector_player, vector_room type) you get the same
exact compiled binary size plus untested code. I think this is the
argument you saw elsewhere?
If you're worried about debugging load times (which I've seen as a
problem moreso), you can look at splitting your project into multiple
dll's, so you only load dll's as you use them at runtime (i.e. with
LoadLibrary()).
