How can you be dry with a programming language that is not reflected?

Question

Any programming language that does not have a suitable reflection mechanism, I find it serious debilitating for rapidly changing problems.

With some languages, it seems incredibly difficult or impossible to do:

• Context setting
• Auto data binding
• AOP / Meta strong programming>

without reflection.

Some examples of languages ​​that do not have a kind of software reflection: C, C ++, Haskell, OCaml . I am sure there are many more.

To show that you can use the DRY (Do not Repeat Yourself) example, which most of these languages ​​violate when you need to write Unit Tests. You almost always have to register your test cases in these languages ​​outside the place where you define the test.

How do programmers in these languages ​​mitigate this problem?

EDIT: Common languages ​​that are reflected for those who do not know: C #, Java, Python, Ruby, and my personal favorites F # and Scala.

EDIT: Two common approaches: toolkit code and code generation. However, I have never seen a toolkit for C.

Instead of just voting, you can comment on why this should be closed, and I will delete the message.
