Why not just initialize the variable where it is declared then?

That'll work too. The only possible "issues" are if you try to reference stuff
in another package here, you have to make sure that package (and everything it
depends on) has already been elaborated. But if its a one-liner, you might as
well just initialize the variable at the declaration and be done with it.
