Re: default instance for IsString

Why are potentially partial literals scarier than the fact that every value in the language could lead to an exception when forced?

My thoughts exactly. In this thread people are using the term "safe" to mean "total". We already overload "safe" too much, might it be a better idea to use "total" instead? (and FWIW I'm not sure I see what all the fuss is about either) Cheers, Simon

You do know, that you already *can* have safe Text and ByteString from an overloaded string literal.

Yes, the IsString instances for Text and ByteString are safe (I hope).

But in order to use them, I have to turn on OverloadedStrings. That could cause other string literals in the same module to throw exceptions at run time.
