After writing some commutative algebra exercises, xy code is not so 
obscure :)

Big problem not only with xypic.
(after grep-ing xp package and context base I found some possibles names

in  core-pos.tex,page-lyr.tex,xtag-ini.tex)

Yes, I love metafun.
But a mp graphic must be preprocessed by mpost for inclusion, and I can 
do it only
if I can execute sysytems commands; this open a security and performance 
issues.

I have posted an idea with XYPic; but \leaders can be used too.
