For next release
^^^^^^^^^^^^^^^^
- vm: add support for all builtin functions
- can't use abs() etc in pipe expression because return type depends on argument type
- pipe operator: allow non-unary function calls in the pipe that specify the other argument(s) in the calls.
- createAssemblyAndAssemble(): make it possible to actually get rid of the VarDecl nodes by fixing the rest of the code mentioned there.
- allow "xxx" * constexpr (where constexpr is not a number literal), now gives expression error not same type
