Programs written in Python are often augmented with programs written in C. Didn't Python become popular BECAUSE it worked seamlessly with C programs? Use both types of languages together. But I'm interested in whether type-inferring languages will ever take off, bringing the best of both worlds, i.e. the code tersity of "dynamic" and the compile-time checking of "static". I'm not sure if types can be changed dynamically in these types of languages, though.
