```
using StringVec = std::vector<std::string>;
std::expected<StringVec, ErrorCode> x;
std::expected<StringVec, ErrorCode> f();
```
I don't know how to see the "Markdown" source you tried. Mastodon's "Markdown" is pretty far from being Markdown but I have been able to get line breaks in code blocks.

I tried it both with backticks and four spaces which are standard Markdown. Here is it without Markdown turned on:
```
using StringVec = std::vector<std::string>;
std::expected<StringVec, ErrorCode> ;
```
using StringVec = std::vector<std::string>;
std::expected<StringVec, ErrorCode> f();
