Error: 'this' is only defined in non-static member functions, not parse

[Stewart Gordon]

For future reference and to elaborate on what others have said, if you're asking for help 
solving a problem with your code, then please:

1. Post a small, self-contained testcase that demonstrates the problem straight out of the 
box.

Tips here:

2. Post full compiler output (or runtime output, if it's a runtime problem) from the testcase.

3. State what compiler version and operating system you are using, as it may be relevant.
