rapid compile times

11.10: adda/translation/rapid compile times:
. during r&d people want quick compiles
(that's what inspired google to create Go.lang);
whereas, one problem with adda
is that in making the lang
easy for the user, and feature-rich,
its compiler might take a long time
trying to figure out what the user wants .
[11.12:
. one remedy for this is integration with adde,
which calls the compiler to attempt tentative translations,
and compiling in sections,
so that if a routine compiles,
and just one line is modified,
only that one line needs to be recompiled .]
. adda can also speed compiles by skipping c,
and translating to addm (the virtual machine).
. addm can do all the safety checks as needed,
rather than at compile-time .
