auto thing = Blah(); // So, what does Blah() return? Oh, right, best go look in the header. Oh, and did I mention 'auto' also consumes constness and pointers too (but not references)? Blah() might return a pointer ... or maybe a const. You'd never guess that by looking at it though.
// Oh yeah, If I changed Blah()'s return type, maybe it still compiles and runs when it shouldn't.
