decorators to annotate functions as commmands

[anirban1c]

something like

@command
@argument('--id', type=int, help='My name', desc='ID of some kind')
@argument('--name', type=str, help='My name', desc='is my name')
createRecord(id, name):
`...

Hi @anirban1c thank you for the suggestion. The Azure CLI was originally written using just such decorators, but we fould it didn't scale well and maintenance was extremely tedious. At least in Azure CLI, many commands had the common arguments with the common metadata, which mean I needed a dozen lines of extra decorator code per command, and if I wanted to update the help text for all the commands, I had to update it in multiple places.

That is the basis for the argument registries in Knack, which follow the DRY principle and avoid all the decorator boilerplate.

am surprised decorators didnt scale ? partials, functools and decorators are legends ! thats what attracted me to python :)
