I'm wondering if Seq can also serve as a general-purpose replacement for Python whenever a fast executable is needed.

(I'm one of the developers on Seq.) We've actually been working mostly on closing the gap with Python for the last year or so. Seq can be useful for plain Python programs as well -- I give a bit more context in my comment above.

It's a domain specific language for bioinformatics. So, most likely not.
