majit-ir: state that no route consumes the FormatSimple tag - #1665
Conversation
The variant's doc said the full-body walker resolves `__format__` on the promoted receiver class and inlines the body for this tag. Only `FormatWithSpec` has a `dispatch_residual_call_iRd_kind` branch; nothing matches on `FormatSimple`, so a FORMAT_SIMPLE stays residual. Records what blocks the route instead: the inline needs a spec operand for the callee's second parameter, and FORMAT_SIMPLE carries none. Assisted-by: Claude

RuntimeHelperKind::FormatSimple's doc said, in the present tense, that thefull-body walker resolves
__format__on the promoted receiver class andinlines the resolved body for this tag. That is true of
FormatWithSpec, whichhas a branch in
dispatch_residual_call_iRd_kind; nothing matches onFormatSimple, so a FORMAT_SIMPLE stays residual.On current main the tag appears only at the site that produces it:
against
FormatWithSpec's producer and consumer:The replacement says no route consumes the tag, and records what blocks one:
the inline needs a spec operand for the callee's second parameter and
FORMAT_SIMPLE carries none —
format_value_dispatchallocates a fresh emptystrper call, which a route would have to synthesize.Comment-only; no behaviour change.
