My $0,02: I was wondering about the merge as well. For my taste, there is almost too much in HOL already as it is. It's not such a big problem, though. You can always build your own custom images with exactly the part you need (not that it's a nice user-interface paradigm, and you need to

Very nice job! Amine. PS: In Reflected Ferrack you start combutation with True, i.e. @{code T}, if the input is @{term False}. Fortunately this does not happen often Even with @{code} we still need to be careful... Florian Haftmann wrote: New ML antiquotation 'code': takes constant as

Quoting Florian Haftmann florian.haftmann at informatik.tu-muenchen.de: There is no urgent need that the HOL image contains *all* the HOL-Complex theories. I also have been thinking about splitting off all the Analysis stuff into a session HOL-Analysis, but on the other hand a lot of

Quoting Tobias Nipkow nipkow at in.tum.de: I don't use Complex, but I strikes me as odd that some of our complex theories should be in the HOL image and other should not be. What is the rational for splitting something off? Only because it is based on NSA? Does a user care how something is

Got it. In which case I agree with the split. Tobias Brian Huffman wrote: Quoting Tobias Nipkow nipkow at in.tum.de: I don't use Complex, but I strikes me as odd that some of our complex theories should be in the HOL image and other should not be. What is the rational for splitting

I see a giant misconception coming. The point of nonstandard analysis is that it makes properties of limits, derivatives, and so forth much easier to prove than can be done with the standard definitions. They eliminate the necessity of arguments involving epsilon and delta. So it would be
