-// TemporaryChange<> is useful for setting a variable to a new value only within a
-// particular scope. An TemporaryChange<> object changes a variable to its original
-// value upon destruction, making it an alternative to writing "var = false;"
-// or "var = oldVal;" at all of a block's exit points.
-//
-// This should be obvious, but note that an TemporaryChange<> instance should have a
-// shorter lifetime than its scopedVariable, to prevent invalid memory writes
-// when the TemporaryChange<> object is destroyed.
