Sorry, but there were parse errors in the watch flakes script. The script I found was:

#!watchflakes
post <- log ~ `panic: runtime error: slice bounds out of range` && log ~ `^\s*runtime/coverage\.\(\*emitState\)\.VisitFuncs

And the problems were:

script:2.74: newline in backquoted regexp

See https://go.dev/wiki/Watchflakes for details.
