Well, there a lot of things that *your personal* library can fix for you.
Should we stop improve the language and start to write just personal libs 
with improvements?
This proposals about the feature that makes Swift better, more enjoyable to 
work with.

Btw, this "with" method you suggest is not replacement for language 
construction - it allows compilation when struct instance constant (let s = 
SomeStruct()) is changed inside block. Do you like this? Do you want to 
produce such an non-safe code to your projects?

No, not best, even not OK. Described above.

As I understand, such a method will have the same problem with un-safe 
behavior in case of constant.
