I am hoping to get some feedback on a new proposal:
The basic idea is to expose syntax that would make it trivial to create a
copy of a Struct instance with an ivar set to a particular value. The
"proposal" I've linked above will give examples and some motivation for the
suggestion. It is a simple gist and not in any way ready for a PR.
Let me know what you think! I'm curious to know if this bit of syntactic
sugar would have value for any of you.
