[Feature] Completion on labelled arguments

[jboillot]

Hello everyone,

I'm adding labelled arguments on a project and I was thinking that it could be great to add automatically all the beginning of the required arguments.
For example:

I don't know if this feature is hard to add but I think that it could be really useful because it's annoying to add again and again the same parameters!
Please, feel free to criticize my idea ;)

Have a good end of weekend!
