using atom myFoo = newFoo() do 
 
    saveFoo( myFoo ) 
 
end using -- tries to delete myFoo but a reference is held in globalFoos, so 
          -- it throws an error ("cannot delete myFoo: too many references") 

I think I'd prefer

atom myFoo = newFoo() 
saveFoo(myFoo) 
myFoo = cleanup(myFoo) -- tries to delete myFoo but a reference is held in globalFoos, so 
                       -- it throws an error ("cannot delete myFoo: too many references") 

Then you could do things like (in Phix/if Euphoria gets try/catch)

try 
   myFoo = cleanup(myFoo) -- (sets myFoo to NULL if all goes well) 
catch e 
   ... 
end try 

Of course you could make the myFoo = part optional/implicit, and/or invoke cleanup({myFoo,myOtherFoo,etc}), or maybe use delete(x,true) where the second parameter forces "last ref" checks
