	str += get_second_string();

	// somehow use the constructed string
	FilePtr file = File::create();

When you perform operations on strings, the results are always stored in the stack.

Source code (C++)

const char *one = "one";
const String two = get_second_string();
// add one string to another
StringStack<> s0 = one + two;
StringStack<> s1 = two + two;

const String file_name = file->getName();
// get an extension if any
StringStack<> ext = file_name.extension();

NoticePay attention to the type of the operation result to optimally use it and avoid issues.
