from https://forum.dlang.org/thread/syseposhefgipogiehvs@forum.dlang.org:

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.
