A high-performance Forth compiler targeting native machine code via Cranelift JIT.

Fast-forth successfully compiles Forth source code to native x86-64 and executes with correct results!

// This works right now!
execute_program("42", true)           → Ok(42) ✅
execute_program("10 20 + 3 *", true)  → Ok(90) ✅
execute_program(": answer 42 ;", true) → Compiles ✅

# Build the compiler
cd /tmp/fast-forth/cli
cargo build --release

# Run tests
cargo test

# Execute Forth code
./target/release/fastforth execute "10 20 + 3 *"
# Output: 90
