// Test 380_004: Optimized Code Generation via Templates
//
// Templates can generate different code based on compile-time parameters.
// This goes beyond Zig's comptime - we generate SOURCE CODE, not just
// instantiate generics.
//
// Example: Matrix operations optimized for specific dimensions.
//   - 4x4: SIMD-friendly, fully unrolled
//   - 3x3: Direct formulas for determinant
//   - General: Algorithmic approach
//
// The template chooses the optimal implementation at compile time.

~import std/math

// Generate a 4x4 matrix type - template knows dimensions, can optimize
~std/math:matrix(rows: 4, cols: 4)
| mat4x4 |> _

// Generate a 3x3 matrix type - different optimizations apply
~std/math:matrix(rows: 3, cols: 3)
| mat3x3 |> _

// Test the generated types
const identity = mat4x4.identity();
const det = mat3x3.identity().determinant();

~std/io:print.ln("4x4 identity created, 3x3 determinant = {{ det:d }}")
