Yes, globals need to be const to be fast. > you can't do > > function foo() 0 end > foo = 10 > > but you can still change the function's definition (so it's methods; > even if the generic remains the same object I guess), and besides, you > can however do this: > > bar = () -> 0 > bar = 10 > > Oh, maybe the fact that foo is a generic function but bar an anonymous > one matters? yes, this just binds a function to a variable. This also works: julia> foo() = 1 foo (generic function with 1 method) julia> bar = foo foo (generic function with 1 method) julia> bar = 2 2
