You can get pretty close with existing Haskell though:

(bin 100010011)

where bin :: Integer -> Integer, and is left as an exercise for the
reader. Obviously its not as high performance, as proper binary
literals, but if you write them as top-level constants, they'll only
be computed once and shouldn't end up being in the performance
critical bits.

Thanks
