As for the code "quality", I can see the code driving certain people

of how much performance can vary depending on how it's coded can be
glimpsed in the graphs in this paper:
If the programmer can simulate a construct faster than a compiler can
implement the construct itself, then the compiler writer has blown it

The object-oriented model makes it easy to build up programs by
accretion. What this often means, in practice, is that it provides a
structured way to write spaghetti code.
