rlang reconciliation

[hadley]

Need to resolve inconsistencies, and make sure only lives in one place. (purrr should probably re-export)

• set_names()
• invoke()
• rep_along()
• predicate functions
• %||%
• purrr::as_function() (defunct in purrr 0.3.0)
• %@% (soft-deprecated in purrr 0.3.0)
• list_along() (soft-deprecated in rlang 0.2.0)
• modify() (questioning in rlang 0.3.0)
• prepend() (questioning in rlang 0.3.0)
• flatten() (vctrs milestone)
• squash() (vctrs milestone)
• splice()

There's also the flatten() functions, which have slightly richer semantics in rlang. And purrr could gain the squash() family as well (recursive flattening).

purrr's %@% needs to be soft-deprecated instead of reexported because unlike rlang's, it uses a non-NSE implementation.

As of today:

#> 10 conflicts:

• %@% is deprecated
• as_function() has been removed
• flatten_*() will be deprecated in Rework flattening #912
• invoke() will be deprecated in Deprecate invoke #911.
• splice() is deprecated

So I think we're done here.
