I'm trying this [Code Golf exercise re digits in a number](http://codegolf.stackexchange.com/questions/22975/print-all-numbers-from-100-to-100-which-contain-a-given-digit). I am unable to combine my two functions into one line ie replace the call of function `includes` in line 2 with the defintion from line 1. Guidance, please ? `includes[v_, d_] := If[Cases[IntegerDigits[v], d] != {}, v, ## &[]] ;
onlyDigits[d_] := includes[#, d] & /@ Range[-100, 100];`
