Created a new example that demonstrates what we need for proper string/type support:
**TextInput Example (currently a counter):**
- Initially tried to build reactive text input
- Exposed 5 critical limitations:
1. String signals stored as i32 (should be i8*)
2. F-string interpolation incomplete (f"Count: {count}" → "0")
3. No oninput event (only onclick supported)
4. No event value passing (can't get input.value)
5. No string operations (len, concat, etc.)
**Quick Fix Applied:**
- Added type coercion in _emit_signal_globals()
- String signals default to i32 0 (temporary)
- Bool signals convert True/False to 1/0
- Example now uses counter to demonstrate reactive updates
**TYPE_SYSTEM_ROADMAP.md:**
Complete implementation plan for proper type support:
- Phase 1: Type hints extraction (already works!)
- Phase 2: Typed signals (i32, i8*, i1)
- Phase 3: String interpolation in text nodes
- Phase 4: Generalized event system
- Phase 5: Component parameter type checking
- Phase 6: Delegate/callback types
This example will drive the type system implementation. Once complete,
text input will work with proper string signals and reactive updates.
