Maybe as a workaround you could use these wrappers:

function matrix alwaysRe(const matrix m)
        return iscomplex(m) ? Re(m) : m
end function

function matrix alwaysIm(const matrix m)
        return iscomplex(m) ? Im(m) : m
end function

I've also noticed that sqrt still doesn't work on matrices with negative
numbers. Of course not strictly necessary, but since the root of -1 is
the definition of i, feels a little strange.
