Using Separate Files

•So when should we use export and when should we simply include our function template implementations in our client code?

•When we have large functions or when their are many type dependencies or specializations, it is often easier to debug our code by using separate compilation units and use the exporting process.

•On the other hand, if we have small function templates, few type dependencies, and limited (to no) specialized templates, then there may be no advantage to compiling them separately.
