When a numeric literal like `0` is used in a polymorphic context (e.g., `[0]`), its type may be a flex var that defaults to Dec during evaluation. Later, when this value is used as an index to List.get (which expects U64), the type gets unified to U64 but the value's layout is already Dec. This caused a panic because asI128() asserted the layout was an integer. The fix adds extractIndexAsI128() helper that handles both int and frac layouts to extract the integer value correctly, converting Dec values by dividing by the scaling factor. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> |
