    Compiled C is faster that interpreted (and scanned many times) M4
code. Some constructs, particularly list processing and call stack
    manipulation, are implemented in M4, but extremely slow.  If they
were implemented as extension in C, the speedup would be tremendous.

Would it make sense to add a feature to M4 which is good for that job?

Yes, definitely IMHO). The problem here is not the lack of understanding of
what could be done (writing the C code for these primitives is actually
quite simple), the problem is more like there is not enough resources
to finish the modular infrastructure Gary started. Once the infrastructure
finished and released, it should be quite straightforward to use it.
