Is this really the case?  The default search path starts with ., and when I 
put an "environ.fs" into the current directory, it loads from there.

path is in the default search order, setpath is in DOS.

The way to go is to use the module system.

module brainless
include brainless.fs
main: go ;
module;

Both.  It's rather the other way round: Being only 30% slower than bigForth is 
a huge achievement of Gforth's approach.
