Highlighting generator expressions

[itavero]

It would be nice if generator expressions can be highlighted explicitly.
Especially when nesting them, it would also be very convenient if the matching starting < and ending > can be highlighted (similar to how parenthesis ( / ) do this, although I'm not 100% sure if this is provided by this extension or something VS Code does it self).

I noticed #8 exists, but I noticed a few time that there was no special highlighting (or it was not evident to me).
