Ha Hans,

at hackerspace Techinc your Modula-2 project has a legendary status.

As I was making my way through some cpp code written for the an esp8266 
based I stumbled on the infamous yield() function. No one in the Space 
could explain what exactly was happening in the program when using this 
The message was that it was a trivial question. Just sprinkle some 
yields{} around the code and the wifi subsystem was kept alive.

I refered to the one loop multi-task loop of the Oberon System.
And from that I told that golang descended from Oberon and before that 

"Hey Modula-2, that is the same weird language that guy uses for his 
home beer brewery. On an Amiga. A real scientist. Everything must be 
exactly measured after the comma."

For them, total representatives of the trial and error programming 
style, writing in Modula-2 was something as archaic as writing 

So, I'm interested in meeting you.
It would be nice to see a working a realtime Writhian system in the
