// To write a pretty-printer test:
//
// 1. Declare a variable of the type you want to test
//
// 2. Set its value to something which will test the pretty printer in an
//    interesting way.
//
// 3. Call ComparePrettyPrintToChars with that variable, and a "const char*"
//    value to compare to the printer's output.
//
//    Or
//
//    Call ComparePrettyPrintToChars with that variable, and a "const char*"
//    *python* regular expression to match against the printer's output.
//    The set of special characters in a Python regular expression overlaps
//    with a lot of things the pretty printers print--brackets, for
//    example--so take care to escape appropriately.
//
// Alternatively, construct a string that gdb can parse as an expression,
// so that printing the value of the expression will test the pretty printer
// in an interesting way. Then, call CompareExpressionPrettyPrintToChars or
// CompareExpressionPrettyPrintToRegex to compare the printer's output.

// Avoids setting a breakpoint in every-single instantiation of
// ComparePrettyPrintTo*.  Also, make sure neither it, nor the
// variables we need present in the Compare functions are optimized
// away.
