A body form in the return slot was blamed at whatever leaf the type parser
gave up on — the [1] in [(defn f [x i32] (+ x 1))], three forms deep — where
the mistake is that the whole form is in the slot. The slot is blamed now and
the parser's own reason keeps its span as a note. Where the parser gave up on
the slot form itself the old shape stands, because a message like 'unit is
written (), not Unit' already names the right thing and leading with it is
better than restating it. The literal -- is an em dash now, like everything
else in the tree.
A one-field case binds the payload itself, so [(match s (Circle c) (.r c))]
reached for a field of an f64 and got a type fact. The binding carries what
the pattern made it, in words, derived at the arm from the case and the
subject; the refusal says the value is already in hand. Set by that path and
nowhere else, so every other binding's refusal says exactly what it said.
The missing collection asserted a thing and contradicted it in the same
sentence — 'is a directory named nosuch somewhere above X, and there is
none'. It states the rule and the two ends of the search instead. The bare
/. it printed was Filename.concat of a directory and a dot, and is cleaned
where the path is made absolute.
