I really like the feature that `knitr` processes everything even if the code has errors. Without `try_silent` the error is printed somewhere inbetween a potentially long list of chunks, I'm not sure how helpful that is. I think my code now offers a nice summary, only we need to print a sensible location for inline chunks (cf. https://github.com/yihui/knitr/pull/651/files#r8088671).
