Representations for values
Opened this issue · 1 comments

IPR needs a representation for values. By values, I mean the objects that result from evaluation of prvalues.
IPR currently has representations for:
- booleans
- strings
- nullptr
- pointers-to-member
IPR does not currently represent:
- integers
- floats
- records
- unions
- arrays

IPR expected clients to use string representation for literals ("universal representation"), but of course that works only in pre-C++03 era, not with compile-time evaluation. Options here range from taking dependencies on external libraries (such as GMP, but with more permissive license) to developing homebrew, purposely-tailored libraries.
aggregate values missing is an oversight. What is needed is not so much the notion of value than that of an "irreducible expression" (which includes values)
