Theres also a single statement rescue that I've only recently learned about.
However, I'm not sure how to specify which exceptions to rescue.

statement rescue value

I recently asked if rescue's should be appendable to any ruby block of

mentioned the single statement rescue, so I'm not sure I was fully
understood.
