Is there any way to have parentheses and brackets that get bigger when "nested"?
For example, normally parentheses and brackets work like in the first case shown in the picture, but I would like to know if there is a way, preferably a package, to have something like the effect of the second case shown in the picture.

\bigl/\Bigl/\biggl/\Biggl(for left brackets) and\bigretc. for right brackets. E.g.\biggl( .. \biggr). – Torbjørn T. Apr 05 '18 at 08:03
