Operator '+' cannot be applied to operands of type 'System.Numerics.BigInteger' and 'double'

This is currently broken:

I tracked this with git bisect quite a bit back, and it seems to have been broken at least since dfa1900, i.e. the first version that built on .NET 5. I don't currently have any .NET Core 3.1 SDK installed so I'm unable to test the older versions (unless I install them manually with perlang-install, hmm...). Suffice to say, this has been broken for a long time.

Just like with #229, this now works better as of #237 being merged:

This is not perfect, but I can live with it. I don't think we need to be perfect in the 0.1.0 release, but we shouldn't have any (known) things with which you can crash the entire REPL/interpreter at least.
