I added string concatenation in PR #33 , so it should now be possible to write string conversion functions.
However, I do not like the idea of a built-in string conversion method. We do not have type classes or any other type of polymorphism. Adding it in a generic way will complicate the language; adding it as a special case for string conversions only will be ugly and complicate the language.

PR #35 adds a builtin method for primitive types and adds support for user-defined conversion functions
