Try this:
is?(integrate(erf(z)*sin(z)^2,z),integral)
which tests that the first expression is a kernel with
the operator integral.

Perhaps this is a little more accurate:
not empty? [i for i in kernels integrate(erf(z)*sin(z)^2,z)
| is?(i,integral)]
which will be true if at least one integral remains.

not empty? [i for i in kernels integrate(1/(a+z^5), z)
| is?(i,rootOf)]

Of course you are most welcome!
