Efficient definition of function which uses fixed allocated constants

And something like the below code does exactly what I want, but I tend to develop by repeatedly executing the code in the same REPL in vscode, so an error is thrown as the const is redefined every time. […]

You can make the function global directly like this:

let A = [1,2,45,3]
    global g(x) = sum(x^a for a in A)
end
