Swift 5.7 improvements

[randomeizer]

I see you have been busy on improving the result builders for 5.7, looks good. Are you thinking about using the new some/any syntax, or is it not particularly helpful in this context?

I am interested in seeing if some of the more excessive parser signatures that I had to wrap in AnyParser just to get it compiling will work better now, since it seems like there have been some under-the-hood performance improvements there too.

@randomeizer Ha just to make sure I understand, what are you referring to us being busy on? 😅

We definitely have a bunch of ideas for 5.7, which includes buildPartialBlock, exploring some syntax, as well as Regex and ParseableFormatStyle integrations.

Anything else come to mind for us to explore?

This branch, specifically: https://github.com/pointfreeco/swift-parsing/tree/swift-5-7, the buildPartialBlock code was most obvious. I will experiment with it a bit soon hopefully - I had some thoughts a while back on a "never fails" parser style, but it was going to require a bunch of generated overloads and didn't pursue it at the time.

Yeah, having some integration with Regex also occurred to me. Looking forward to the performance comparisons also ;)
