CTFE parsing is especially useful for DSEL (Domain Specific Embedded Languages) or internal DSLs. The advantages are:

1. Syntactic errors (in the parsed constructs) are given out at compile time.

2. D reflections are available only at compile time. Referencing the variables/identifiers in the parsed subset of DSL with the mainstream D code is impossible without reflections in place.
