TIL that there's a format called wat, which means "WebAssembly text format" and it can be converted to wasm (and back to wat).

This format uses S-expressions like lisp, and it's got a stack machine like forth. [1] [2]

I'm a bit surprised something so mainstream ended up being a lispy forth.

In case you're not aware, I believe that web assembly is a stack based language.

TIL that TIL means "Today I Learned".

Thanks for reading the post :)

Update 2020-12-07: There was a bug in the macro expansion logic. I've backported the fix to the linked source and explained the bug in the 'mistakes' section.
