What you are trying to create is a Domain-Specific Language. The rationale behind this kind of (programming) language is: keep the syntax as simple as possible, while simple refers to "human readable", by removing all non-needed features.
Difficulties of C-Syntax
What makes C-Syntax hard to write:
- Missing trailing ;. I saw many beginners curse on this one.
- Missing } or ).
- The concept of pointers (you probably won't need this one)
- Variable scopes
So if you take a small subset of language features, it will make the code both easier to read and to write.
Example
let's say, the code needs to express that Process A is dependent on Process B.
Process A = "Cook something";
Process B = "Go shopping.";
depends_on(A, B);
or:
Cook something <- Go shopping
Technical Complexity does influence usability
In the end, what may be at least as important: a decent compiling/debugging environment, error messages that help to solve the actual problem, etc. And because of the technical difficulty of parsing C, its compiler often throws errors that are only faintly related to the real cause. So a simple syntax will help here, too.
