Kind of irritating when you come across a z-encoded name containing a z where you don't expect z-encoding.
I'm curious as to what you mean by "where you don't expect z-encoding." The assembly symbols would seem to 'qualify,' or do they turn up elsewhere as well?
Well, you'd expect it in the generated assembly, so you're prepared. I didn't expect z-encoded names in source files (in comments, of course). compiler/CgPrimOp.hs has a few pretty ones, e.g. -- #define unsafeFreezzeByteArrayzh(r,a) r=(a) emitPrimOp [res] UnsafeFreezeByteArrayOp [arg] _ = stmtC (CmmAssign (CmmLocal res) arg) -- #define sizzeofByteArrayzh(r,a) \ -- r = ((StgArrWords *)(a))->bytes emitPrimOp [res] SizeofByteArrayOp [arg] _ = stmtC $ CmmAssign (CmmLocal res) (cmmLoadIndexW arg fixedHdrSize bWord) so that caught me off guard. I particularly like sizzeof :D
