10 print *, bessel_yn([1, 2], 2.0)

12! Wrong, transformational function:
13! Does not pass check.c -- thus regarded as wrong generic function
14! and thus rejected with a slightly misleading error message
15 print *, bessel_yn(1, 2, [2.0, 3.0]) ! { dg-error "Too many arguments" }

20! Wrong in F2008: Negative argument -- and no need for a GNU extension
