Immutability

[mnapoli]

What do you think about making strings immutable? I.e. methods would always return the result without modifying the original object.

It would make much more sense IMO.

For example:

if ($str->toUpper() === 'HELLO') {
    // ...
}

Here $str would be modified, which is confusing.

(and the if wouldn't work because it returns void obviously)

The main issue here is about performance. For many cases it could be too
expensive to do it.

On the other hand, it would be nice to have these method be fluent.
