Probably about half of my functions/metods are tagged with 
"nothrow". And as ".dup" becomes nothrow and few more functions 
become nothrow (iota, etc), that percentage will increase. I have 
also proposed to add to Phobos some nonthrowing functions, like a 
maybeTo, that help increase the percentage of nothrow functions:
