Thanks for this answer.
Problem I'm trying to solve is the following:

I use 'make_suite' which is a program that do regex matching on source
code to extract a list of function that looks like OUnit tests; from
this list, it write an ocaml source code file which is a test case
that call all the previous functions found.
(see: http://skydeck.com/blog/programming/unit-test-in-ocaml-with-ounit/)

Now, instead of having a program which write a source file that I have
to compile and run, I would prefer if I can change 'make_suite' to
create the test case and run it directly.

Thus, I have a list of function's names as string and I would like a
list of functions.
Is this possible?
Is there a better way to achieve automatic test case construction?

PS: this is not a *real problem* to use an intermediate file; just
wanna learn if we can do without :)
