//! Basic KQL syntax validation
//!
//! Demonstrates checking queries for syntax errors without schema awareness.
//!
//! Run: `cargo run --example basic_validation`

    let validator = KqlValidator::new()?;

    let result = validator.validate_syntax("StormEvents | where State == 'TEXAS' | take 10")?;
