Re: [PATCH v3 10/16] qapi/expr.py: Remove single-letter variable

[Markus Armbruster <armbru@redhat.com>]

Why?  Is it to appease a style checker?

I disagree with a blanket ban of single-letter variable names.

If @f is deemed too terrible to live, then I'd prefer @feat over
@feature, because it's more visually distant to @features.
