Is there any possibility to define default parameters as a dictionary or something similar?

I have a function

```julia
f(a;b=1,c=2) = a+b+c

```

Now I would like to define b and c in a dict structure like this:

```julia
params = Dict(b=>2,c=>2)

```

to be able to call

`f(1,params)` or `f(1,params...)` or something similar.

That would come in handy 😉

Thanks in advance!

`f(1; params...)`

Thanks. That symbol thing makes more sense 🙂 I’m not into it but it definitely sounds reasonable.
