from https://forum.dlang.org/thread/[email protected]:
For some languages the IDE will show info about a closing bracket so one knows how it is grouped.
The idea is that either a shadow comment is added or a popup when highlighted/selected is shown over the closing bracket which displays the first non-empty line above the opening bracket:
statement
{
} // statement
// statement is a shadow comment(not part of the source, grayed out a bit, or a popup)
Helps a lot with lots of nesting and one doesn't have to manually add them which isn't robust.
