how to do comparisons for each object type?

to get a boolean

• logical/vector of logicals: ==, all(x == y)
• character: identical(x, y)
• factor: coerce to charcter as.character then proceed
• integer: identical(x, y)
• numeric: identical(x, y)
• list: ?
• data.frame: visdat::vis_compare() ?
• matrix: ?
• function: identical(x, y)
• environment: ?
• all other custom classes: user provide a function/callback to do the comparison, via $compare()
