I do not want to evaluate the expression in the string at compile time. I want to parse it at compile time and later at run time, I am required to process the parse tree and evaluate it in a different fashion (using binary decision diagrams).

In summary, I need CTFE to parse the expression and create a parse tree from it. I think this requires a string mixin that takes the expression string as input and outputs code that builds the corresponding parse tree.
