string/[]byte casting:
    The []byte(s) is not a cast but a conversion. Some conversions are the 
    same as a cast, like uint(myIntvar), which just reinterprets the bits 
    in place. Unfortunately that's not the case of string to byte slice 
    conversion. Byte slices are mutable, strings (string values to be precise) 
    are not. The outcome is a necessary copy (mem alloc + content transfer) 
    of the string being made. So yes, it can be costly in some scenarios. *No 
    encoding transformation is performed. The string (source) bytes are copied 
    to the slice (destination) bytes as they are.

key indexes: 
    integers will ALWAYS outperform string or []byte keys when it comes to 
    comparison and matching.
