Thanks for reporting.

Could you point me to the documentation that describes the syntax of these variables in PL/SQL? I haven't been able to find this info by myself. The best I've managed to find is this page but it doesn't describe the syntax, only the usage.

I searched for a long time and couldn't find anything better than the chapter 5.3.1 Rules for Placeholder on your site.

Yeah, but this section says nothing about $ and # characters.

Yeah, but this section says nothing about $ and # characters.

You have right.
There is also:
Placeholder-Expressions
Database-Object-Names-and-Qualifiers.
The second says:

Nonquoted identifiers can only contain alphanumeric characters from your database character set and the underscore (_), dollar sign ($), and pound sign (#). Database links can also contain periods (.) and "at" signs (@).
