After sticking my neck out and being shot out out of the sky by the big
guns.....................................

I heard from a lecturer in 1990 that compilers were built by writing a
language subset compiler in assembler (or C or C++ or.....) and then by
using that subset to step by step extend the language to its desired form.

And he was really clever he was , he had glasses and a beard and everything.
