Precisely, Modula-3 is a systems programming language just as capable  
as C.  To that end, a goal of any language implementation is to "eat  
your own dog food" and implement as much of the language in itself as  
possible.

There are some C sources that adapt to C library and system functions,  
but generally use of C is discouraged in the Modula-3 implementation.
