Current dplyr version is: 

function(x, y, tol = .Machine$double.eps^0.5) {
  abs(x - y) < tol
}

Should this be a generic, i.e. do we have some metric of proximity for other types ?

Probably just need to use vctrs recycling rules and check that x and y are numeric?

Might want to prepare a little checklist of funs functions — like confirm recycling and types? Maybe documentation should have some standard way of describing?
