Error Handling with TRY/CATCH

Use TRY / CATCH to handle failures and optionally retry operations.

Catching failures

TRY riskyCall()
CATCH(e) -> { err: e.message };

If riskyCall() throws, the fallback block produces an error object.

Retrying

Add RETRY n TIMES to re-run the expression before giving up.

TRY fetch(row.id)
CATCH(e) RETRY 3 TIMES -> { err: "failed" };

The call is attempted three additional times. If all attempts fail, the fallback runs.
