fuchsia-default-arguments-calls

Warns if a function or method is called with default arguments.

For example, given the declaration:

int foo(int value = 5) { return value; }

A function call expression that uses a default argument will be diagnosed. Calling it without defaults will not cause a warning:

foo();  // warning
foo(0); // no warning
