    ...program (like small integers, Python caches strings of length one in most cases). Stop, said my friend, before you get into negative times - this is fast enough for my program. I agreed, though I had wanted to try one more approach: write the whole function in C. This could have minimal storage requirements (it would allocate a string of length N right away) and save a few instructions in the C code that I knew were there in the array module, because of its genericity (it suppor...

This weakness is currently reflected in all three of my test re-implementations.

Virginia is the worst of all choices, because that state has passed the UCITA law, which adds a whole new range of risks and burdens in the distribution of free software. We explained all this to CNRI, but it was the other subject on which they were immovable. So we settled f...
