This gist had a far larger impact than I imagined it would, and apparently people are still finding it, so a quick update:

  • TC39 is currently moving forward with a slightly different version of TLA, referred to as 'variant B', in which a module with TLA doesn't block sibling execution. This vastly reduces the danger of parallelizable work happening in serial and thereby delaying startup, which was the concern that motivated me to write this gist
  • In the wild, we're seeing (async main(){...}()) as a substitute for TLA. This completely eliminates the blocking problem (yay!) but it's less powerful, and harder to statically analyse (boo). In other words the lack of TLA is causing real problems
  • Therefore, a version of TLA that solves the original issue is a valuable addition to the language, and I'm in full support of the current proposal, which you can read here.

I'll leave the rest of this document unedited, for archaeological


Just some notes and references for myself.

  • In bash, you can access your C:\ drive via /mnt/c/
  • ~ = C:\Users\MLM\AppData\Local\lxss\home\mlm and is different from your Windows user directory C:\Users\MLM

Let's say you're starting a new Yii project and you've already created the database schema for it using something like phpMyAdmin or MySQL Workbench. Now you want to create an initial database migration so you can put the schema under version control, but you don't want to manually write the Yii code to create the tables, indexes, and foreign ke…
