Text File Writer Assignment
Background
Ensure
Ruby provides begin/rescue/ensure which is rather analogous to try/catch/finally in Java.
note: although coincidental, it is rather fitting that this reference covers begin/rescue/ensure with ensuring to close an opened file as its example. Ensuring to close an opened file is the canonical example for this sort of feature.
Yield
