Hi Peter,
sorry for the delay. Fabian just remembered me to explain this.
The reason for the string optimization is to optimize performance issues
of Internet Explorer regarding string operations (concats, compares,
switches, ...). When someone use constants (uppercase static keys) we
think that they are already used as constants and are optimized through
this usage already. This also reduces the size of the global map from
unneccessary strings (which don't need this optimization).
HTH,
Sebastian
