It is better because:
- it does not pollute the headers
- it can differentiate between link time and run time access. I.e. you
can have a versioned symbol that you can link and run against, or you
can have a versioned symbol where you cannot link against, but you can
run an existing binary.
There are probably more things to say here, but these are the first ones
that come to mind.
