-ddump-parsed shows the program after parsing. All operator application are parsed *left-associative* with one precedence. Then the renamer re-associates them to respect precedence and associativity.

yes, in that case, would anyone mind if I find an easy way to change GHC to parenthesize those non-infix uses of operators? :) hmm... maybe _I_ would mind, since it makes "what GHC is doing" just a tiny bit less transparent to the user of -ddump-{rn,parsed}. :-)
I fixed an identical bug in a copy of the code a few months ago. http://haskell.org/pipermail/libraries/2007-April/007317.html Unfortunately, I think TH was forked off from the in-compiler syntax tree too long ago for my fix to be useful... Stefan
