Thanks for filing this @vitoyucepi!

This is indeed a bug. I'll fix the docs soon.

Note that this is a new function that hasn't made its way into a release yet, so you'll have to compile gomplate yourself to be able to use it.

I have no plans to use this feature yet.
I came here because the slice function was deprecated in #1464. I use it in {{ tmpl.Exec "sometemplate" (slice "val1" "val2") }}.
Though I think it'll be acceptable to use coll.Slice instead.

Yup, exactly. coll.Slice is what you want where you used to use slice
