as_task_xxx should enable setting weights ect

[sebffischer]

I think making this work would be a good user-friendly change, what do you think?

iris$weight = runif(150)
task = as_task_classif(iris, target = "Species", weight = "weight")

@mllg What do you think? It might be a little tricky with column roles that can (meaningfully) have more than 1 role.

[mllg]

What about the other column roles like order, stratum, group or name?

[sebffischer]

See my comment above. I think this is actually not a great idea.

[mllg]

But weight can also be a feature?

[sebffischer]

yes, my comment was in general that this is not really a good idea. I am closing
