In a sentence of this kind, in a programming environment:
This construct is "in a self explanatory manner" not interpretable, since it raises an ambiguity over the language´s syntax which is not determinable by the language itself.
"Obviously" would fit the case of a clear wrong syntax, but this one is not obvious (to (self) explain), although self explanatory (explained stating the (self) obvious).
Especially, I do want to judge the explanation as obvious, without judging the mistake as obvious.
As an analogy for the english language, how should I say:
The syntax "You I call" is "obviously" wrong since undetermined, however, the same syntax "Answers I need" is clearly interpretable, although "in a self explanatory manner" a wrong syntax, since the language by itself can not determine that Answers don´t need you.
