I wanna say no but why allow this in a constructor parameter?

Lol, np

second reaction - lol that's crazy
I really didn't think this sort of thing is allowed and now I'm about to abuse the hell out of this 😈

Btw, 
compareBy
is a function taking a vararg of functions: https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.comparisons/compare-by.html

@Nate but can a 
vararg
only be referenced within an 
init
block?
@ilya.gorbunov Interesting, I'll have to see how that's implemented. this is definitely a rabbit hole worth diving into!

you can declare it as 
vararg val functions
to be able to use it elsewhere

oh my, I was mixing up the order! thanks!
Also, I looked into the comparator functions.... I wish I could write something as elegant and beautiful. With more time I can!
p
It is just syntactic sugar around Array<(String) -> String>
