>Regarding your second comment- you're correct of course, but what makes this a "blind spot"? After all, if the user is writing code in Python, they're doing scientific computing in Python, regardless of what the Python library calls behind the scenes.

What he means is, they can't expand the core primitives provided for them in Python itself, so they are constrained by what's given if they want performance. Unlike with, say, Julia.

I think Nimrod could really make inroads in those cases. Almost as easy to write as (and in fact looks a lot like) like python with lightweight type annotations, runtime characteristics are those of C, since that what it compiles via.
