    Writing grammars? Next week's Comma release will help you do that more efficiently! ⏩ Navigate quickly between parse rule and action method with Ctrl+Alt+Home (either direction) 😻 Captures from the rule are auto-completed in the action method

  17. Doing some testing of this month's upcoming Comma release. It will offer parameter info for `use`d modules from outside of the project, introspecting them and showing all possible multi candidates. For examples, here it is on redirect from Cro::HTTP::Router.
