I understand that from a technical perspective, the mandatory BEGIN...END you always need in a PL/pgSQL function, is a new block, and the variables declared are perhaps technically in a new block, at a deeper level than the IN/OUT variables. But I would still argue the expected behaviour of PL/pgSQL for a new user would be to consider the IN/OUT variables to be in the same block as the variables declared in the function's first block.
No they are not. Teaching a new user to consider them as the same is simply wrong.
The parameters belong to a block that matches the function name. The outermost block has a different name if supplied (I usually use <<fn>>), or is otherwise anonymous. Lots of code quite correctly relies on this, including some I have written.
This isn't a mere technical difference, and there is surely zero chance that we will label use of it an error under any circumstances.
