Inane features a language happens to have, like object-orientation, are marketed that are not backed up by any argument or example beyond homework-level code.
What language features do users say helped them? Existence of libraries didn't make C a good language, and providing a binding to those libraries does not make Python a good language. Hard work must go into bindings, whether for Python or for Ruby or for Lua, but Ruby and Lua make convincing cases for themselves.
