I see typed global variables as replacement for writing
const x = Ref{Int}(1)
and then mutating it as `x[] += 1`. With the type annotated globals, we'll be able to simply write
x::Int = 1
and rebind it as `x += 1`. Besides the syntactic advantage, this way is threadsafe by default whereas mutating a constant global `Ref` is not threadsafe.
