What is the difference between sourcing a script file and evaluating an inline script string?

Sourcing a script file, via source(), loads and runs a script's contents from a separate .bsh file, which is well suited to reusable logic that's maintained as its own file and potentially shared across multiple other scripts or test plans.

Evaluating an inline script string, via eval(), runs a script provided directly as a string in code, which suits short, one-off logic, especially dynamically constructed script content that doesn't exist as a saved file at all.

The practical tradeoff is maintainability versus convenience: a sourced file can be edited, versioned, and reused independently of wherever it's called from, while an inline eval'd string is quick to write for something small but becomes harder to maintain and reuse as its complexity grows, since it typically lives embedded directly inside whatever configuration or code is calling it.
