Hi community.

It is (more or less) known that when defining a metric one can provide a parameter `signature`

, e.g +1 for Riemannian metrics or -1 for Lorentzian metrics; and it is also known that one can parametrise the epsilon tensor with a metric.

I'm interested, however, in a generic epsilon tensor defined for a Lorentzian signature... without specifying a metric (because I want to consider spacetimes with diferent dimensionality). I tried the following, and it seems to work:

```
\delta{#}::KroneckerDelta.
\epsilon{#}::EpsilonTensor(delta=-\delta).
```

## Question

Is the above proposal equivalent to assigning a `signature = -1`

to the epsilon?
