I have done something similar too. Though I use the word "use-script"
instead of "do". This way I can redefine use-script
according to the context the script is running in.

That's an interesting idea. I could already use "use-script" as my marker
for script replacement.
Another interesting idea is that in the same replacement fashion, use-script
could create a function definition that makes a Rugby call.
Romano had this idea:
import librarydir db-select
; will do the file librarydir/dbms.r
In this example import provides a naming service - it searches the library
for the function. Plus it runs the file.
I'm also unsure how the mooted rebol modules functionality will impact on
this.
So some interesting ideas:
Where does your function definition live? [ in a block, in a script, in
rugby ]
How do you find it? [Using a naming service, a consistent directory
structure, etc.]
