Here are some random tips from me. I'm also a Factor newbie so take it
with a grain of salt:
* Don't use vectors because normal sequences works just as well.
* Be functional! Avoid words that mutate data structures because they
make the code harder to reason about.
F.e. this piece of code in mdls:
"mdls" 1vector swap suffix!
can be written as just:
"mdls" swap 2array
Another example is your mdutil word:
:: (mdutil) ( flags on|off volume root/owner -- seq )
root/owner 1vector "-" flags append suffix!
"-i" suffix! on|off suffix! volume suffix!
It's a great showcase for local variables but can be better written
without array mutations:
:: mdutil ( flags on|off volume root/owner -- seq )
root/owner flags "-" prepend "-i" on|off volume 5 narray
