Is (catch #t (lambda () (use-modules (xxx))) ...) OK?

Is this an effective way to test for the existence of a module, and if
so, will a second (use-modules ...)  be required to actually get an
effect on the top-level envt?  i.e.

  (if (catch #t (lambda () (use-modules (xxx)) #t)
                (lambda (key . args) #f))
    (use-modules xxx)
    (do-something-else ...))

or is the use-modules inside the catch sufficient?
