SNIP Unfortunately, that undermines the high abstraction advertised by Mathematica. Mathematica should hide this. I think it doesn't because of the mentality "everything is an expression". Seems that Mathematica's greedy evaluation leaves no breathing room for more careful consumption of large expressions (bad manners). I've noticed similar tendencies in Workbench's syntax parser.
