When aggregating using `min` or `max`, as a user I would like to do the following:
```
max(v1, v2, v3)
```
rather than
```
max(max(v1, v2), v3)
```
Therefore it might be useful if `min` and `max` supported more than two arguments.
Use case: [https://gist.github.com/sungwoncho/ddba3a287ad87288331c493c2de5a5cb#file-get\_active\_answers](https://gist.github.com/sungwoncho/ddba3a287ad87288331c493c2de5a5cb#file-get_active_answers)

[martinmr](https://github.com/martinmr) _commented_ :
Update: I tried working on this and I got some basic math expressions to work with min and max using more than two arguments. However, there are some bugs in the parser that are caused by the need of knowing exactly how many arguments a function needs. Since this is a very basic assumption, I would need to rework the entire parser, which requires a lot more work than I initially thought.

Assigning to @pawanrawal to see if he has better luck with this than Gus and I did.
