Code that does not compile is generated

[danr]

Using 4.1.0.0, I have gotten code generated that looks like this:

kj_s1ii = (\ b#_aUa -> (let {
wild1_X1x = ((M19.>#) b#_aUa 2#) ;

However, b#_aUa is not one identifier, it falls apart as the two identifiers b# and _aUa in GHC, yielding a type error. The pretty-printing instance for Name is to blame here. (But maybe this is fixed in the latest version?)
