I guess there is. Perhaps by changing BeginPackage["boo`"] and EndPackage[]
into Begin["boo`"] and End[] will avoid the actual context specified in
Begin to be loaded into the list of available contexts.
Begin["Boo`"]
Boo`
foo=12345;
End[]
Boo`
foo
foo
Boo`foo
12345
So a (rather explosive) file named Boo.m containing
______________________
Begin["Boo`"]
foo=12345;
End[]
______________________
and loaded with Get
<<Boo.m
should do what you want, I guess.

I don't think so. Mathematica reads all package contents in one single gulp, AFAIK.
You can define a 'package' for each single function and load them one at the
time. I guess it is possibile to define 'stubs' to do that with packages.
Perhaps it's possibile to extend this method even to files thas use Begin
instead of BeginPackage. Or, better yet, maybe using ordinary packages
and then removing their contexts just after they have been loaded,
could solve your problems.
Have a look at the documentation for Contexts, Begin, BeginPackage and
DeclarePackage. I am sorry I can't help you more right now (time is a harsh
master : )) ), but I hope these hints can be of some help, anyway.
cheers,
Peltio
