Not that I approve of this, but you would need to overload binary + to recognise when it is called in void context. Otherwise my $y = $x + 1; would modify $x with chaos resulting. I don't think there is a way to do that in the manner of wantarray
.

When you write a method that overrides a binary operation (like add), the method gets passed three arguments - the two operands and a third argument which tells you if the operands have been swapped (for code like 1 + $obj). If this third argument is undef then the original statement is in void context.
