Hi Alexander,
I'm glad you're taking a look at Factor - the feedback is nice to get.
Factor and Forth share similar-looking syntax, but Factor has a different
set of internals and primitives that it builds with, for things like GC and
arbitrary-sized integers (a bit like a "high level memory managed Forth",
but maybe less like a "Forth"). It does have a good optimizing compiler
that is able to make fast code in many cases, but we have not spent a lot
of time on making the "minimal binary" smaller. Probably we should do that
sooner than later. You can see that in:
IN: scratchpad "hello-world" deploy
That gives you a "hello-world" binary of about 1 MB. The "factor" binary
itself is about 480k, I think. So in general I agree with you that we could
use some trim-the-fat pull requests.
Best,
John.
