Errors can be caught and shown, explicitly. Errors that are thrown but not explicitly will stop the markdown generation.

```ts eval --error --meta
throw new Error("def");
```

throw new Error(/* message: */ "def");

Error: def

Error blocks are eventually wrapped in a try-catch block, and have scope rules accordingly.

We can create a variable with const in an error block…

const a = "abc";
throw new Error(/* message: */ a);

Error: abc

And later create another const with the same name.

const a = "def";
a;

"def"

And a third time, we can re-create the const.

const a = "abc";
throw new Error(/* message: */ a);

Error: abc

The “a” variable was never changed.

a;

"def"
