What could I change that to such that blobs are allowed as the second

This did the trick. But I have another question...
In easy ffi, if a function parameter type is 'double', then it expects
you to pass a SRFI-4 'f64vector'. Under the covers, this is just a blob.
So my question was about how to pass a blob directly. And all is well.
My new question is, is there a way to specify a type such that the
function will accept a blob *or* some SRFI-4 vector? I.e. if you pass a
SRFI-4 vector, you'll benefit from the nice type checking. If you pass a
blob, it works but you don't get the type checking.
For example, if the type of a parameter is 'double', the ffi check goes
as follows. If the argument is a blob, it's sent directly. Otherwise it
*must* be an f64vector. Something along those lines.
