Unexpected `matches` behavior

[jumarko]

I came across a surprising matches validator behavior: it marks a value as valid when only part of the value satisfies given regex:

(b/valid? {:name "ab"} {:name [v/required v/string [v/matches #"\w{1,2}"]]})
;;=> true

(b/valid? {:name "abc"} {:name [v/required v/string [v/matches #"\w{1,2}"]]})
;; should be false
;;=> true 

(re-matches #"\w{1,2}" "abc")
;;=> nil

;; even worse if we expect only digits
(b/valid? {:name "abc123def"} {:name [v/required v/string [v/matches #"\d+"]]})
;;=> true

Is this an expected behavior?

Is the expected usage pattern that we should use^ and $?

(b/valid? {:name "abc123def"} {:name [v/required v/string [v/matches #"^\d+$"]]})
;;=> false

(b/valid? {:name "123"} {:name [v/required v/string [v/matches #"^\d+$"]]})
;;=> true
