Re[3]: [Ecb-list] semantic does not handle Qt "slot" keyword

[Eric M. L. <er...@si...>]

Hi,

Thanks for the example.

I also found the dilemma with the label possibly throwing an error
which I was able to fix.

My concern with adding support for SLOT, is that it is a QT keyword.
As I described below, it could really mess up other programs.

As for making it an optional item, I'll have to see if it can be done
without messing up other programs.
