Broadcast and custom expressions / instructions

Great video. Thanks for creating great content explaining how all of this stuff works!

These are the topics i was waiting for but they are too much for 7 min , now i finally learned how to use them but not exactly why i need to use them. i'm sure they can save time and ease the programming process or maybe even some desired tasks may not be possible without them so i hope you point these things whenever possible in future, for me i don't mind longer videos and i hope other audience are like me. Thank you
