sx('1 2 "c", d') # returns c("1", "2", "c", "d")

#> [1] "1" "2" "c" "d"
sx('1 2 3') # returns c("1", "2", "3")

#> [1] "1" "2" "3"
sx('1 2 "3"') # returns c("1", "2", "3")

#> [1] "1" "2" "3"
sx('1,2|3.4') # returns c("1", "2", "3.4")

#> [1] "1"   "2"   "3.4"
sx('01 02') # returns c("01", "02")

#> [1] "01" "02"
