...is another man's economy of effort.
I probably couldn't count the number of times I've heard systems being
criticised for carrying around a lot of 'legacy'. It's one of the criticisms
of Windows that one hears very often, and is also applied to systems like
Linux with its monolithic kernel.
It seems ironic to me that someone on an Oberon list should consider it
economy of effort to have an Oberon bobbing about on top of Linux like a
cork on the ocean.
