I don't understand what you mean.  Guile can load .so modules, that
doesn't make it a non-free software promoter.

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.

It seems like this statement is based on a completely wrong idea about
what I meant.
