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. [*]

[*] And I'm not convinced the cost/benefit ratio is right. Vim's
lightning fast handling of superficially similar effects is very
persuasive.
