Not all decisions in Python are based purely on the "explicit enough" 
thing. Some things in the language cannot be explained using 
explicitness alone. So, when we cannot fully explain the ' why 
String+1.75 ' question with statements about explicitness then it 
doesn't mean that anybody lied or wrote something wrong. :-)
