My understanding from the RFC is that that the grouping is not relevant, 
the `_` is stripped regardless.

I would expected this all to work the same

- 1_000_000     => 1000000
- 100_0000      => 1000000
- 1_0_0_0_0_0_0 => 1000000

It even gives similar examples with the hex variant:

0x42_72_6F_77_6E; // with separator

Am I wrong?
