To say perform/@ (ph - phrase): (- if (0==0) {ph} -).
This causes the compiler to crash with the “I have no bloody idea what happened…” error. I think the code can be in the text, but invoking it with a
say "[perform now Donald Trump is in Prison]"
type construction causes the noncompile.
I believe it worked in 6L02–I pulled the line from the source of Transparent which was released in 2014. It is not in Baker of Shireton which was 2015, but it’s possible I had started out using it and had to take it out. I know I had to write it out of Easy Doors and update. So it must have been 6M62.
EDIT: I’m wrong. It is in Baker of Shireton, but it can’t compile because Easy Doors no longer has the magic line.
