The four the defvar review left behind, plus the two the author's dogfooding
notes name.
A three-element defvar that is neither a type nor a value gets a paragraph
about the fork it stands at, and the paragraph is right for the name that
genuinely could have been either. Three names cannot: a data case, which is
a third thing with its own spelling; a name another language uses for a type
this one has; and a plain type typo, where a confident one-edit suggestion
was turning a line into four. Each answers first now.
A bracket form never reaches that fork at all — the parser gives it the type
reading outright — so a value name inside one landed in [resolve_name] and
came back as a lecture about generic code. Both readings at the element that
decided it, and the dyn spelling it offers is checked to be a real form.
[int] is two edits from [i32] and so outside the one-edit net, correctly:
two edits is a guess. But the name is not a guess, it is what four other
languages call the default integer, so a short list answers it by name.
Nothing goes on that list without one honest answer — [char] and [void] are
off it, and the comment says why.
A parameter called [i] is not a mistyped [i8]. The machine types size
themselves in the name, so a typo keeps the digits and a parameter name has
none; that is the rule that stopped (defn idx [v i] dyn ...) being refused.
A type written in a two-element defconst was reported as an unknown name,
because that form has no type slot and the brackets read as an array
literal. A type name inside one is unambiguous — a type and a value cannot
share a name here — so it says what happened and names defvar.
Two register warts alongside: no message cites a repo filename at the reader
any more (plan.org in three, spec-memory.md in one).
