# bugprone-lambda-function-name

Checks for attempts to get the name of a function from within a lambda expression. The name of a lambda is always something like `operator()`, which is almost never what was intended.

Example:

    void FancyFunction() {
      [] { printf("Called from %s\n", __func__); }();
      [] { printf("Now called from %s\n", __FUNCTION__); }();
    }

Output:

    Called from operator()
    Now called from operator()

Likely intended output:

    Called from FancyFunction
    Now called from FancyFunction

## Options

IgnoreMacros

  The value true specifies that attempting to get the name of a function from within a macro should not be diagnosed. The default value is false.
