nit: Why the need to make this a macro? Can't it be a helper function?

[f(malita), 2013/06/20 18:48:15]

The only reason I went with a macro was to be able to pass a token-pasted
parameter to EXPECT_TRUE, and get a more informative message in case of failure
(containing the actual missing parameter name). Maybe it's not worth it, or
maybe there's a better way?

gtest.h defines the AssertionResult class which looks like it would fit the role
(there's a few examples there).

That's perfect, thanks!
