  ...comprehensions and further improves their performance (about 35%). Implemented rich comparisons for floats, which seems to make comparisons involving NaNs somewhat less surprising when the underlying C compiler actually implements C99 semantics. Optimized list.extend() to save memory and no longer create intermediate sequences. Also, extend() now pre-allocates the needed memory whenever the length of the iterable is known in advance -- this halves the time to extend the list. Optimized list res...

• Computer Programming for Everybody

  Computer Programming for Everybody Computer Programming for Everybody This is the text of a revised funding proposal that we sent to DARPA in August 1999. In March, we heard that at least an earlier version of the proposal was accepted by DARPA; the work has begun late 1999 and will hopefully last two years, although we've only received funding for the first year (through October 2000). We're keeping our fingers crossed for the rest. Unfortunately, the move of the Python developm...
