Alt Text: (For searchability): 3 part comic, drawn in a simple style. The first, leftmost panel has one character yelling at another: "@+_$^P&%!. The second comic has them continue yelling, with their hands in an exasperated position: "$#*@F% $$#!". In the third comic, the character who was previously yelling has their hands on their head in frustration, to which the previously silent character responds: "Sorry, I don't speak Perl".

Also relevant: 93% of paint splatters are valid perl programs

So, this uses a macro, but if you're thinking anything is possible with a macro, it's actually not in Rust. The input does still need to parse as valid Rust tokens.

Which means the authors asked themselves at some point: Is the Rust syntax a superset of the Python syntax?
And well, it's not. In particular, some Python keywords will just be tokenized as an identifier (like a variable name).

But it is close enough that the authors decided against requiring a massive string to be passed in, which does amuse me. 🙃

Context: jest is a Javascript testing library, mocking is something you do in test in order not to use production services. AI understood both terms in a none programming context
