Should I use quos or enquos ?

[kwstat]

According to https://tidyeval.tidyverse.org/multiple.html:
Quoting multiple arguments can be done in two ways: internal quoting with the plural variant enquos() and external quoting with vars() .

But the following functions all use quos()

dplyr:::filter.tbl_df
dplyr:::arrange.tbl_df
dplyr:::select.data.frame

So, is quos() or enquos() preferred?

Internal: enquos(), external: can be vars() or quos() (as vars() is an alias of quos()), but we will prefer vars() internally going forward. The functions you've mentioned actually need to be updated to use vars() so that we're consistent.
