fix(UnusedVariable): recognize destructured lambda parameters as used#9015
Merged
Conversation
…#8942) Destructured lambda parameters (e.g., `forEach { (a, b) -> }`) were incorrectly flagged as unused even when they were used in the lambda body. Changed to use KaVariableSymbol instead of KaLocalVariableSymbol to properly resolve references to destructured parameters. https://claude.ai/code/session_017k8v2kYDUuqB72jZ76Hmvf
The lambda parameters need explicit types for the Kotlin compiler to infer the types correctly. This fixes the compilation error in the test. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
