How about: "Lars agrees with Thiago"? ;-) More seriously: constant global tables are perfectly fine. But I fully agree with Thiago that I want to avoid adding more global static data (using Q_GLOBAL_STATIC). Reasons are that those are initialised at startup with an undefined initialisation order (and usually worse: destruction on application shutdown). They thus add overhead for each application (in terms of memory usage and startup time), and can cause headaches on shutdown if there are cross dependencies between global statics (we've had those in the past).
