Test:

verify an extension built on top of the ItemWrapper: a function which remembers the last result. As a simple test, we bind a static helper function to produce a random value and remember the result returned last.

void verifyFunctionRefResult ( )

inlineprivate

Test:

verify an extension built on top of the ItemWrapper: a function which remembers the last result. Here we use a test function, which picks a member of an vector and returns a reference to it. Thus the cached "result" can be used to access and change the values within the original vector. In a real world usage scenario, such a function could be an (expensive) data structure access.
