Is this preferred design pattern?

ref int b() { return a; }

It's okay, but I'd prefer an alias, because your snippet uses the heap
needlessly (it puts variable a into heap to make sure there will be no
stack corruption if you pass a pointer to function b() outside the
main() function)
This is not true. You can annotate main with @nogc.
