Why use "left" and "right" for scalable brackets?
Why use "left" and "right" for scalable brackets?
I'm wondering why the words "left" and "right" were used for scalable brackets. Isn't something like "scale" making more sense and making things easier?
Re: Why use "left" and "right" for scalable brackets?
Because you need to "close" the brackets, thus the need to indicate which one starts the pair ("left") and which one close it ("right").
Remember you can make all brackets scalable: From a Math object, under Format → Spacing → select Brackets under Category → check the corresponding option → Press Default button.

Well, actually, I already knew the answer and my question was more a rhetorical question than a real one.
You see, contrary to LaTeX (if we want to compare it with LaTeX because this "left/right" pairing idea seems to come from LaTeX), the brackets in OO Math are already required to match each other: eg ( with ), [ with ], langle with rangle, etc, etc
Having this bracket-pairing requirement, "left" and "right" word-pairing is simply superfluous.
Not only this "2nd level" (left-right) word-pairing is superfluous, it makes reading and editing very tough. Haven't you ever changed mind and needed to change a simple bracket pair into scalable one? In some situation (and for me, this sadly happens quite often) where there are a lot of brackets, it's a pain in the *ss to find out the other matching bracket!
Sorry to say, but this "left/right word-pairing" was a very bad idea to start with.

The solution was my last sentence I wrote there: "I really think it would be good to have some solitary brackets."keme wrote:... then what with the ISO notation you mentioned in that other thread?
All is a question of occurrence. I could bet that unmatching brackets only represent less than 5% (or even less) of all practical use cases. Now, having left/right word-pairing, users are forced to use them in 95% of use cases! (Well, to be honest, not all brackets are required to be scaled, so the percentage is actually less than 95%, but certainly a lot more than 50%).
What an upside-down world!
