In Python, one may a clear a dict as follows
```julia
d = {1:'a'}
d.clear()
```
In Julia, I’d have expected a similar workflow along the lines of
```julia
d = Dict(1=>'a')
clear!(d)
```
To my surprise, there seems to be no such function clear!(), neither for dicts nor sets. I guess there’s a good reason for this, and likely some best practices to achieve the same outcome. I’d be interested in both. Thanks a lot!

It’s called `empty!`.
