Visual D show the opening bracket info for closing bracket

[Michelle Long]

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.
