Hey would like to work on this, I am getting a hang of the repo after working on cast send

[mattsse]

cool, assigned @dipanshuhappy

@grandizzy @mattsse two ways i can do this.

1. I change the args with Vec
2. I parse the fields string into "," or "-".
   The first one will cause changes in tests and other calls of the block function, the second one is a quick fix rather than a proper fix.

Edit: I meant Vec

[mattsse]

@dipanshuhappy I think reasonable here would be a Vec for multiple args, either delimiter but also just separated by whitespace should work I think

That approach would change inputs to the function and also little refactor in tests. If thats acceptable then i can go ahead with that.

yep that sounds fine
