Oh no please no. Of course a variadic function can always be rewritten as a
function that takes an array. Of course. You always can use an array. Got it.
But some APIs are nicer with varargs. And even nicer APIs go over the top by
adding support for arrays too, because not all lists are known at compile time.
It’s a matter of being sensible.
DatabaseTable.select(id, name).order(name, id) // What’s the
problem?
// vs.
DatabaseTable.select([id, name]).order([name, id]) // OK, of
course... But some people will find it a litle short
