I would be tempted to say than for big projects, you usually build specific
libraries and tools for your project, kind of another language layer.
One this is done, and if done well, it increases the expressivity of the
language you use, whatever the language is, and so, reduces the difference
between languages.  For medium sized projects, the layer of specific
libraries is thinner, and you then observe more directly the expressivity
of the bare programming languages.
