I think, given the usage statistics, we'll find that these amount to small
nips and tucks. I can't speak to whether things will be to your taste, but
please rest assured that these proposals do not arise out of anyone's taste
or distaste (outside that of the core team). If taste were the basis for
proposals, I'd be proposing rather larger changes to the syntax, but I
appreciate that my personal taste is of no import.

But as to interests, please do speak loudly and without reserve if any
proposed changes are putting a stop to real-world (or even anticipated)
uses you have. That's precisely what this process is about.
