The problem you're going to have with something like
m4 is indentation. When you inline a function call,
somehow the inserted code has to be shifted to the
same indentation level as the statement containing
I don't know of any off-the-shelf macro processor
that can handle that sort of thing easily.
You may want to consider writing a custom one in
Python. You could use the ast facilities to parse
the code, operate on the parse tree and then write
it back out as code.
You might be able to get some ideas from 2to3,
which does similar kinds of source-to-source
