I made a video explaining a concept I love called macros, which allow you to add your own syntax to a language. Languages like Rust, Lean, and lisp have them. The goal with the video is to make you feel like you could've discovered macros yourself.

I'm new at making educational content like this, but I'm planning on making many more programming language videos like this one on my channel. Any thoughts, constructive criticism, or advice is more than welcome! Hope you all enjoy

We are pleased to announce Rhombus 1.1 is now available from https://rhombus-lang.org

Rhombus is a general-purpose programming language that is easy to use and uniquely customizable.

As of this release:

• Add annot and annot.def as ways to define an annotation without directly writing meta-time (i.e., macro) code.

• Add as as a binding form, which is sometimes more readable for naming than using && and provides a way to shadow an identifier that is bound as a binding form.

• Change class to bind inherited names using the corresponding superclass or interface reference.

• Change space.enforest to adjust scopes in the same way as for a macro transformer when applying an identifier handler.

• ffi: Add an initialized-array variant of new.

• pict: Change explain_anim to add a ~label_as argument. Change Pict.rebuilt to replace as rebuilt, and also add a ~as_rebuilt argument to select the old or new bevavior. The Pict.rebuild method also supports ~as_rebuilt. Improve magic_move and cross_fade to better handle paragraph points and multiple instances of a child pict.

• slideshow: Add slide_transition and continued page numbering.

Thank you to community members who contributed this release.
