- rafaelvasco 8y agoYeah , but i meant that a = multiply_by_2(a) still looks like it is copying things even if it isn't. Let it be immutable by default and mutable with a keyword.
- runeks 8y agoFor what it’s worth, if you can optimize away the immutability (copying), I’d much prefer expressing myself this way, rather than using mutability.
