Suboptimal z-encoding of tuples
Symbols for tuples aren't always properly z-encoded. E.g. `ghc-prim_GHC.Types_$tc'(#,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,#)1_closure` is z-encoded as `ghczmprim_GHCziTypes_zdtczqZLzhz2cUz2cUz2cUz2cUz2cUz2cUz2cUz2cUz2cUz2cUz2cUz2cUz2cUz2cUz2cUz2cUz2cUz2cUz2cUz2cUz2cUz2cUz2cUz2cUz2cUz2cUz2cUz2cUz2cUz2cUz2cUz2cUz2cUz2cUz2cUz2cUz2cUz2cUz2cUz2cUz2cUz2cUz2cUz2cUzhZR1_closure`
Test and fix incoming.
