- Unfortunately, IST is provably not as powerful as 'full' nonstandard
- analysis. In particular, you cannot do 'nonstandard hull' constructions
- in it, and many of the important results ("important"="important to
- standard analysis, and without known standard proofs") in the
- last decade using n.s.a. have used these hulls.
