Scheme regular expression match

Question

Is there a simpler way of writing in scheme

(eqv? (regexp-match "0x" "0x1234") #t)

#f

(eqv? (regexp-match "0x" "1234") #f)

#t

Answer 1

That would be

(regexp-match? #rx"0x" "...some-string...")

Note that the #rx means that the regexp is precompiled and included in your code. It's also better to do that since it protects you from writing confused code and swapping the arguments.

BTW, something like

(regexp-match? #rx"^0x" "...some-string...")

is probably more useful.
