Help with map match

[swedebugia <swedebugia@riseup.net>]

Hi

I'm trying to learn how to check in guile if a node package matches one 
of the items in my blacklist.

First version was with (member pkg-name blacklist) and it worked but 
forces me to write down all the blacklisted packages which is tedious 
when I can just regex match if it begins with the same name.

Now i'm trying to do the same with match and I could not find any 
examples or guides on the subject that I understood. :-/

blacklist
$1 = ("matcha" "webpack" "rollup-plugin-node-resolve" "browserify" 
"electron" "statsd" "vega" "grunt-release" "lineman" "lineman-angular")

I want the procedure to return #t if a match is found and I want it to 
match if it begins with the same e.g. "rollup-plugin" should match 
"rollup-plugin-node-resolve" and return #t
Else #f

This did not work:
(use-modules (ice-9 match))

(define x
         '("ts" "test"))
(map (match x
         ("test") #t)
         (else #f) x)

Any ideas?
