remove reload

[StefanKarpinski]

Send reload the way of the dodo – and workspace. Now that Revise is the way to do this sort of thing, perhaps we should get rid of reload as well. Both require and reload are soon going to need to pass in a context module in order to determine what the meaning of the name argument means, so this is going to have to change API in any case. See also #25046, #25166.

TIL there is (was) a function called reload

reload is still very helpful for cases where Revise won't work

[rdeits]

I actually use reload almost daily, precisely for the situations where Revise doesn't work (for example, when I change a type definition). Restarting Julia instead is ok, but can involve waiting minutes for things like Plots to compile (I realize that there's a ton of work underway to make this situation better in the future).

What is the suggested workflow when developing a new module and modifying the types in that module? Should I just include() the module file instead of using reload? Or just restart Julia?

[StefanKarpinski]

I can look at adding this back after I've done my code loading changes, but it's going to need a different API because a name can no longer unambiguously determine a module. You need at least the module from which reload is being loaded. In short, the previous reload cannot be done.

[rdeits]

That makes sense. I'd have no issue calling some other function with a more precise argument than just the module name as long as there's some way to reload a module without restarting Julia. Thanks for all your work on this!

[StefanKarpinski]

It may be possible for the API to be reload(Foo) where Foo is the actual module object.

[rdeits]

That would be absolutely perfect.
