What is the most straightforward way to make a variable in the global scope that can change it's value, but not its type? So far I use this:
const GLOBAL_VAR = [MyType] # array with single element set_global_var(x::MyType) = GLOBAL_VAR = x get_goval_var() = GLOBAL_VAR This works fine and preserves type stability, but looks quite unintuitive. Is there more standard container or another way (e.g. type assertions or something) to handle such cases?
