Hi,

yes we are aware of that. We could explicitly accept float and double as "valid_index_type", but I think this would just keep silent some latent bugs. I've just added note there: http://eigen.tuxfamily.org/index.php?title=3.4

Cheers,

Hey everyone,

I noticed that in the development branch the following code will no longer compile: https://godbolt.org/z/pHPX2j

Aside from the fact that I think this is a bug, this would break a lot of code I think.

Best regards

Janos
