  • ctfeInterpret

    Declaration

    Expression ctfeInterpret(Expression e);

    Entry point for CTFE. A compile-time result is required. Give an error if not possible.

    Discussion

    e must be semantically valid expression. In other words, it should not contain any ErrorExps in it. But, CTFE interpretation will cross over functions and may invoke a function that contains ErrorStatement in its body. If that, the "CTFE failed because of previous errors" error is raised.
