[hosers-talk] Celebrity Deathmatch: Programmer v. Compiler

["Jon Stewart" <stew1@xxxxxxxxxxx>]

A long, long time ago, I wrote a complete hack of a function that did some 
ridiculous thing with c-style strings, something on the order of 
usefulness as reversing a string in place. It attempted to waste no 
cycles, and it pretty well succeeded (I think I even used a goto to save a 
statement). Josh said it should be featured on the television series "When 
Programmers Attack".

Now, many years later, I am still attacking. Unfortunately, my 
competition has more than kept pace with me. When I say:

  #define TEST_FIXTURE(testname, fixtureType) \
    void testname(fixtureType& fixture); \
    static AutoRegister UNIQUENAME(testname)(TestRunner::TestPtr(new 
      BoundTest(boost::lambda::bind(&BoundTest::RunFixture<fixtureType>, 
      _1, var(testname), _2), #testname))); \
    void testname(fixtureType& fixture)

you'd think the compiler would pretty much shut up and take it like the 
bitch it is. Instead, I get back:

(Actually, I get back a lot more than this, but it's a good sample.)

Sigh.
