**N.B.**: on the platforms that don't support specifying process exit codes, this primitive may either do nothing, exit the program the usual way supported by the platform or trigger a global interpreter restart.
### `hseval` (Host Language Evaluation)
### `hseval` (Host Evaluation / Execution)
- **Stack Effect**: `( expr -- val )`
- **Description**: Pops the string `expr` from the stack, evaluates it as an expression in the host language (e.g., Python), and pushes the resulting value back onto the stack.
- **Description**: Pops the string `expr` from the stack and evaluates or executes it in the host environment.
- In the Python implementation, it evaluates `expr` as a Python expression and pushes the resulting value back onto the stack.
- In the Go implementation, it executes `expr` as a system shell command, redirects its stdin/stdout/stderr to the current process, and pushes the command's exit code back onto the stack.
**N.B.**: this primitive may not be supported on all targets. Only use as a last resort in controlled and/or sandboxed environments. Never pass user input to this primitive.
