>  compiles in about 6 seconds. If I remove the import of the Trait 'ATrait' in 'AClass' the compile proces only takes about 1 second.
> If you consider the classes as the are shown above then the compile time nearly duplicates for every method call I add to the chained method call.
> With the replaceAll with alpha24 being compiled the compilation process takes approximately 11 seconds and with alpha 25 being compiled in conjunction with alpha24 the compilation takes approximately 20 seconds.
