Curious: since spaCy is a commercial project (I know that it is open source), did you consider writing it in C or C++, it would make binding to other languages a lot easier. I can imagine that importing the Python runtime can be problematic in some projects. Also, I assume that you will see some Python types in the API when you want to call the parser from C?<p>(My own NN dependency parser is written in Go, since it&#x27;s mostly for research, but if I wanted to make it embeddable, I&#x27;d have implemented it in C++ or Rust with a C API.)
