; Fieldtest — Floats milestone, axis 4: reach for float_to_str.
|
|
;
|
|
; Natural task: build a label like "result = <float>" by concatenating
|
|
; a Str prefix with the float's text. The LLM-author who looks at
|
|
; `ail builtins` sees `float_to_str : (Float) -> Str`, reaches for it,
|
|
; and gets a codegen-deferred error per DESIGN.md §"Float semantics":
|
|
;
|
|
; `float_to_str` (Float → Str) is type-installed but codegen-
|
|
; deferred to a follow-up milestone: ... Calling it typechecks but
|
|
; produces a structured `CodegenError::Internal`.
|
|
;
|
|
; This fixture pins the reach-and-bounce. Expected: `ail check`
|
|
; succeeds; `ail build` fails with a clear, structured codegen error
|
|
; that names `float_to_str` and points at the missing runtime path.
|
|
;
|
|
; (No string-concat builtin exists either; we just print the result of
|
|
; float_to_str directly via io/print_str. The first failure point is
|
|
; codegen, before any concat would be needed.)
