I can't read ordinary lisp, but Nemerle's macros seem pretty damn easy to 
me:

And note that deconstructing the tree typically makes use of Nemerle's 
excellent pattern-matching:

I've long been of the opinion that Nemerle's CTFE, macros and pattern 
matching make D's counterparts look terrible in comparison (too bad Nemerle 
doesn't do low-level).
