        Yeah... and I've already demonstrated the 'almost' part.

It's one of those:

function _include_h { return "source <liblookup>$1" ;}


alias include='eval $( _include_h "$1")'

Near as I can tell, you can't do that in a function.
If you source a file in a function, the local vars in the file
would be local to the function -- not to the prog using the alias


I thought I did suggest that line be corrected -- so people wouldn't
think functions replace aliases...
Since for some purposes, functions cannot replace aliases.

Now that I've justified another usage (similar to previous that eval'ed a 
result), -- how about how do I export aliases??
