ARGV eval parameters should be same type as the script (String or byte[])

Bug Report

In RedisScriptingCommands, the generic V (corresponding to the values stored in the cache), is used as the argument type for the values that are passed into the ARGV Lua variable. But, these arguments have no direct relation to the data stored in the cache. Because the only use of these arguments is in the script, they should have the same type as the script (as discussed in #1010, the script type will be changed to String or byte[]).

These aren't keys either. So basically, every approach is potentially wrong. One might want to use plain strings, other people put in JSON or use any other serialized format. That being said, we're not going to change ARGV from V to something different.
