Code highlighting is not optimal
The code snippets are code-highlighted, but it looks like the highlighting ignores its job halfway through a snippet.
In particular, primitive types are rendered in the same way as the callout to indicate the line number.
One cannot distinguish between a callout and a simple number with a lot of spaces in the code.
In the olden days, a similar piece of code was rendered as
with clear differences between the code and the callouts, although the not type defining lines are similarly boring.
