But... in a dynamic language each variable must have an associated type
information? So, why can't you use LLVM struct consisting of
- integer type code (or anything else you like)
- pointer to void which holds the actual data.
What you're doing is rather interesting. There's IronPython which implements
Python (a highly dynamic language) on top of .NET and which claims to be 2x
faster than regular Python. However, I never seen any implementation details
so don't know how dynamic features are dealt with.
