What tips do you have for golfing in Wierd? Tips for golfing other languages don't seem to help one golf Wierd programs so I'm looking for ideas that can be applied to code golf problems that are specific to Weird - especially if it helps me reduce the size of this answer at "Hello, World!"
Don't forget about self modifying code
As Dennis showed in https://codegolf.stackexchange.com/a/142785/24812 a loop can be much shorter than a linear program and that there are clever ways to exit the loop. The spec makes it clear that a 90 degree angle allows you to choose one of two different directions at runtime. Dennis showed that you could modify the program at runtime - with amazing results.
