Currently yr_era(x) == yr_era(y)
is used in several places but I don't trust it.
It also might be better to only selectively compare eras, e.g. consider eras with different labels equal if all the significant parameters are the same. Then they should be able to be combined, with a warning that the labels will be changed.
