// Describing Parameterized Matchers
// =================================
//
// When defining a parameterized matcher, you can use Python-style
// interpolations in the description string to refer to the parameter
// values. We support the following syntax currently:
//
// %% a single '%' character
// %(*)s all parameters of the matcher printed as a tuple
// %(foo)s value of the matcher parameter named 'foo'
//
// For example,
//
// MATCHER_P2(InClosedRange, low, hi, "is in range [%(low)s, %(hi)s]") {
// The last argument to MATCHER*() is a string-typed expression. The
// expression can reference all of the matcher's parameters and a
// special bool-typed variable named 'negation'. When 'negation' is
// false, the expression should evaluate to the matcher's description;
// otherwise it should evaluate to the description of the negation of
// the matcher. For example,
//
// using testing::PrintToString;
//
// MATCHER_P2(InClosedRange, low, hi,
// string(negation ? "is not" : "is") + " in range [" +
// PrintToString(low) + ", " + PrintToString(hi) + "]") {
// return low <= arg && arg <= hi;
// }
// ...
// EXPECT_THAT(3, InClosedRange(4, 6));

// would generate a failure that contains the message:
// would generate two failures that contain the text:
//
// Expected: is in range [4, 6]
// ...
// Expected: is not in range [2, 4]

// If you specify "" as the description, the failure message will
