Makefiles is one example. Shell script containing snippet(s) of
Python code is another one.
At one time I also tried to make a simple "configuration file"
engine based on Python for a big Framework used in one physics lab.
Idea was to have a Python extension for that C++ framework and
to configure the Framework from Python code, like:
# Module means C++ Framework module, not Python
Module1.param1 = "a string"
Module2.paramX = [ 1, 2, 3 ]
# etc., with all Python niceties.
People who were using this Framework were all hard-core physicists,
some of them knew Fortran, many were exposed to C++. There were
few other "languages", some of them home-grown, used for different
tasks, but none of these mentioned languages ever placed so much
significance on the whitespaces. There were some big surprises for
people when they discovered they can't arbitrary indent pieces of
the above configuration files because it is all Python code. Add
here space/tabs controversy if it is not enough yet to confuse
poor physicist fellows :) I think that config file project was killed
later in favor of less restrictive format (I left the lab before that,
can't say for sure.)
