misc-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
