You have created a constant applicative form (commonly abbreviated CAF). GHC assumes that all top level declarations are constants, and simply does not garbage collect them.
FUD! CAFs are definitely garbage collected, in fact we have a big lump of code generator and runtime complexity (Static Reference Tables, SRTs) to ensure that they do. However, GHCi doesn't always GC CAFs, perhaps that's what you meant. Cheers, Simon
