Indeed. The "constructor" in that example is the equivalent of the
Python __init__ method. The "initializer" is not a part of the class
at all but just a syntactic sugar for creating an instance and setting
some of its properties at the same time in a single statement. It's
very similar to the C array initializer syntax, e.g.:
int myArray[] = {1, 2, 3, 4, 5};
