The following is totally unimportant, but I feel compelled to share:

I implemented this once, long ago, for Python 1.5-ish, I believe. I got it to the point where it was only 15% slower than ordinary Python, then abandoned it. ;) In my implementation, "cells" were real first-class objects,

That shouldn't matter to speed via any first-order effect, unless you also used accessor functions instead of direct reference to get at the data members.

and "celldict" was a copy-and-hack version of dictionary.

Hmm.

I forget how the rest worked.

Anyway, this is all very exciting to me. :)

Don't worry -- it will run much faster if Guido codes it. One key difference is that Guido will run each cell in its own thread .
