mojo packages announcement (A Mojo package is defined by placing an __init__.mojo or __init__.🔥 within a directory)

Hi, it looks like mojo packages (basic support for importing) was announced on 2023-07-20. Very excellent add!

Mojo now supports packages! A Mojo package is defined by placing an init.mojo or init.🔥 within a directory. Other files in the same directory form modules within the package, this works exactly like it does in Python, for example...

1. This does not seem to be mentioned in the mojo docs, or programming manual? Seems like a useful thing to add!
2. The jupyter playground does not seem to facilitate really creating and editing mojo files. I did manage to create a .text file and rename it as .mojo, and got syntax hiliting after that.
3. Importing does not seem to work. I noticed with this in the playground. Not sure I am missing something obvious. Or should I file a bug?

Here is a silly struct which works OK defined in a notebook:

However, when importing the same struct from a mojo package, it raises some errors:

At the moment you need to explicitly import things in the .mojo file that are usually imported by default:

from SIMD import Float32

This issue was raised and closed as completed just today: #469

That usually means that it'll be in the next release, should be in the next few days.

thanks @mojodojodev that worked.
