creator-applications.md: Improve readability of source code comment

[Flowdalic]

One can not easily identify the start of the "code section" in "same as new StringBuilder()". Instead, use a colon to separate words from code.

I agree that a colon is missing here, but I think // same as: new ... would be better than // old: .... "Same as" carries extra information (both sides are identical), where as "old" makes it sound like a refactoring...

[Flowdalic]

I deliberately decided against // same as: new because it gives the impression that both approaches are equal. However the Motivation for Universal Apply Methods states that leaving out new "makes code more pleasant to read.", and hence should be preferred. This is why I tried to discourage the usage of new by calling it "old".

How about

StringBuilder("abc")  // legacy: new StringBuilder("abc")
StringBuilder()       // legacy: new StringBuilder()

But then again, I do like old, as this describes a old way of doing things.

OTOH, I am aware that this could be considered nitpick-ish and it is definitely subjective. So, what should it be?
