This is confusing. How about "A type parameter which references Self in its default value was not specified.".

"Here is an example of erroneous code"

There will be a debate on this sentence every time, right? :)

I won't agree with you on this one. I think it's too much "decoration" for such a simple sentence.

Currently it's not a sentence, though. Neither is "Erroneous code example", but that reads more naturally so I'm mostly okay with that.

Arf, people will never agree on this sentence. We should put the debate on the RFC as well.

I don't currently have an opinion about whether the phrase in question needs to take the form of a sentence or not, but I do have an opinion about the supposedly more natural alternative of "Erroneous code example":
The phrase "Example of erroneous code" is at least unambiguous about what is erroneous: the code itself.
The phrase "Erroneous code example" is less clear.
-
The adjective "Erroneous" could be interpreted as applying to the word "code", as in:
here is some code that illustrates the error under discussion
-
or it could alternatively be interpreted as applying to the word "example", as in:
here is an attempt at an example of some code to illustrate concept X, but the example is erroneous, and thus the example fails to actually illustrate X
(Of course one has to actually work to come up with the latter interpretation. Nonetheless, I'm generally -1 on phrasing that slip too easily into multiple potential parsings.)

Isn't the issue that there needs to be // at the beginning of line 3438?

Oh right! I totally overpassed it... Thanks @pnkfelix!
