Why do you use @generated functions?

This line confuses me, why do you need the && part if you have it covered by the else clause?

EDIT: just deleted my proposal for a faster version , If you remove && x == y your code works as you intended

2nd Edit: I finally understand @generated functions :slight_smile:
if you follow my first suggestion you might compare too different types as equal if they have the same number of fields
with the same name.
This solves the issue:

@generated function ≂(x, y)
    if !isempty(fieldnames(x)) && (x.name == y.name)
        mapreduce(n -> :(x.$n == y.$n), (a,b)->:($a && $b), fieldnames(x))
    else
        :(x == y)
    end
end

in a generated function anything that is not quoted is just its inferred datatype, got it now.
