First you say that an int as a struct is slow, possibly ugly, can't be optimized, etc. etc.  But then you turn around and say that modern compilers can make a user-defined complex type efficient.  Which is it?  It doesn't feel like the article comes to any kind of conclusion.  Is it that fundamental types like int and float should be builtin, while anything higher-level including complex can be done satisfactorily as a library?

the link time code generation is powerful.  It can optimize it very well as fast as built-in. I guess it's what that article means.
