Phew. I can't be the only person who worried there was an issue with the QT toolkit. This is something less important.

Some choose short variable names that they can type fast (this might be correlated with vi programmers).
Others choose long variable names that are more descriptive (this might be correlated with emacs programers).
Personally I chose the latter, because copy-paste is easy, and ambiguity can be confusing.
But ambiguities are great fun for making puns and dadjokes.
