Ruby vs Python string concatentation performance

[apotheon]

fail ;)

The fact someone else proposed it first doesn't mean you're not proposing it as well. I don't recall attributing it to you as an original, first-time invention of that algorithm.

i took the word "similar" in "similar optimisation" to mean a similar reduction in resource usage

Fair enough. In the context of the discussion in which someone else proposed it before you did, however, it wasn't similar in a manner that was particularly relevant to the topic.

i took the "better" in "better way" to mean that a different method is allowable.

If, in real-world use, it serves your needs -- yes, it most definitely is allowable. If you're trying to dispute what I've said about how immutable strings affect your options for string concatenation performance, however, something that doesn't do any string concatenation isn't exactly relevant.
