That's not my primary worry. Some of the crazy stuff we import uses
pascal, so you have numbers like 3,7e5

So now we need to parse exponents too.

I'd be more inclined to say "let's replace the comma with a decimal
point instead, and try to re-parse the number, and see if we get
further. The downside of that is that we're changing the buffer we get
passed in. Nobody cares, but still, it's kind of ugly. It's simple,
though. Attached.
