Is it possible to improve performance if the router could convert string to bytes using to_slice? From the benchmark, to_slice would cost <4 nanoseconds and efficient to compare using == ``` Range 17.51M ( 57.11ns) (±10.77%) 32 B/op 14.44× slower Slice 252.8M ( 3.96ns) (± 5.81%) 0 B/op fastest ``` Range: key[0..-2] Slice: (key.to_slice)[0,key.size-2]
