dsn <- system.file("shape/nc.shp", package="sf")
nc <- st_read(dsn)

wkt <- readLines(system.file("shape/nc.prj", package = "sf"))
sf:::CPL_crs_from_wkt(wkt)

mls <- "POINT (20 30)"

x <-  sf:::gv(dsn)

We need "agr.R", "sf.r" and "sp.R".

nc <- st_read(system.file("shape/nc.shp", package="sf"))
Reading layer `nc' from data source `/perm_storage/home/mdsumner/R/x86_64-pc-linux-gnu-library/3.3/sf/shape/nc.shp' using driver `ESRI Shapefile'
converted into: MULTIPOLYGON
Error in st_sf(x, ..., agr = agr) : object 'NA_agr_' not found

We need sp.R for st_as_sfc generic.

op st_intersects is a problem, so will have to hack the slice [
