Today's a good day to brush off the old web blog. Here's an article about a weird tip used by Clang and the Swift runtime to reduce the launch time and memory use costs of reflection data structures: http://duriansoftware.com/joe/Optimizing-global-constant-data-structures-using-relative-references.html

@BasThomas

Swift JIRA tickets now have "votes". Not sure when this was added.

I made a custom public filter to sort by highest voted bugs/issues.
https://bugs.swift.org/issues/?filter=11015

[BasThomas]

@jessesquires I think that's been there forever. 😁

[jessesquires]

@BasThomas lol oops 😳
