1) Is the comparision with `=' or `<>' of structured variables okay in ISO Pascal? ISO 10206 6.8.3.5 only says that the types to be compared must be compatible.
If not, this might be a reasonable extension (already offered by some compilers, *not* including Borland Pascal;).
I don't know what is okay in ISO Pascal :-(. But I do have a simple question. How do you want to compare structured variables? Compare member by member? I knew a very fine programming language (ELAN) in which it was possible to define your own operator (`=', `<>' or whatever you wanted). Is it possible to have this as an extension to Pascal?
