Native languages for web development

Why are "native" languages* almost never used for web development? Shouldn't FastCGI be just as good as what web servers do with Perl or PHP? What am I missing?

* languages designed for AOT compilation to opcodes like C++, Ada, C, D, Pascal, or Go

It makes sense to me. Sometimes you don't know if a variable like last_name or email is going to hold a string or a number, so you have to add run-time checks. JavaScript adds the run-time checks for you, freeing your mind to work on more important things, like writing callbacks.
