Code action: suggest to create missing parameter as local binding

[jkone27]

Details

When developing code, often we first write some parts and later we "fill them in" with implementations, one example is method parameters, would be great if one could just write the name of the method parameter, and then have a contextual action to create the parameter of the specified type, with maybe for now just the option as a local binding, maybe it could be adjusted to provide more options:

• Local binding (within the same scope)
• upper scope binding (module or global if a script..)

example

generate a code suggestion here / action , to generate the non existing local binding for the parameter

This is a great idea, I'd love to see an initial version of a codefix for this if you want to create one!
