`validate::contains_exactly()` detects invalid syntax but `contains_exactly()` doesn't

[SteadyGiant]

validate::contains_exactly() "fails" (warns there's invalid syntax, 0 confrontations). contains_exactly() works as expected. Other functions work fine with the validate:: bit. Is this a feature or a bug? I use <package>::function() for stylistic reasons.

library(validate)

tb = data.frame(x = c(1:3, 2), y = 4:7)
tb2 = data.frame(x = 1:2)

# This fails
rules1 = validate::validator(
  validate::contains_exactly(tb2[, "x"], allow_duplicates = TRUE)
)
#> Warning: Invalid syntax detected, the following expressions have been ignored:
#> [001] validate::contains_exactly(tb2[, "x"], allow_duplicates = TRUE)
validate::confront(tb, rules1)
#> Object of class 'validation'
#> Call:
#>     validate::confront(dat = tb, x = rules1)
#> 
#> Confrontations: 0
#> With fails    : 0
#> Warnings      : 0
#> Errors        : 0

# This works
rules2 = validate::validator(
  contains_exactly(tb2[, "x"], allow_duplicates = TRUE)
)
validate::confront(tb, rules2)
#> Object of class 'validation'
#> Call:
#>     validate::confront(dat = tb, x = rules2)
#> 
#> Confrontations: 1
#> With fails    : 0
#> Warnings      : 0
#> Errors        : 1
