...ou only have access to (poorly documentated) headers, and signatures like
foo(int* const a, int b);
are not easy to interpret at first sight.
Imho, references are as good as pointers when no (re)allocation nor rebinding (in the sense explained before) is needed. Moreover, if a developer only use...
Injecting $state (ui-router) into $http interceptor causes circular dependency
..., do
this.$rootScope.$emit("unauthorized");

Example 3
x = ['foo', [1,2,3], 10.4]
y = list(x) # or x[:]
y[0] = 'fooooooo'
