no i didn't test it

context has two different versions of \define, there is one in 
syst-ext.mkii/syst-aux.mkiv
which has no parameters but prevents you from overwriting a existing 
command (there \redefine
with allows this) and another one in core-sys.mkii/mkiv which replace 
the first one and has
support for parameters but replace on the other side the old definition 
(you get only the
terminal message)

the question is, which behavious is correct, replace the old macro or 
keep it, in my
opinion \define should leave the old definition untouced and \redefine 
should be used
in this case (but we need a version with parameters)
