Naming/MethodParameterName AllowedNames support for as

[bkuhlmann]

Describe the solution you'd like

This is a small request for adding as to the default list of AllowedNames.

Describe alternatives you've considered

The alternative is to manage my own list of allowed names. Example:

Naming/MethodParameterName:
  AllowedNames:
    - as
    - at
    - by
    - db
    - id
    - in
    - io
    - ip
    - of
    - on
    - os
    - pp
    - to

Notice that I include as in the list above which is the only exception to the current defaults.

Additional context

I often find that I'm using as as a parameter for functional composition in Ruby where I need to have a parameter that allows me to message an object as a different representation of itself after being operated on. Example (truncated for brevity):

use my_command, as: :to_h

The above allows me to delegate to my_command with a #call message which answers an object that can be converted to a hash via the as: :to_h parameter. The use of the as parameter allows me to have short and succinct syntax for pulling this off.

That makes sense. e2c1298 has updated this default configuration.
