Mm, I don't know how to debug that…

Just so… :)

More. In 1.8.7:

> (array? 1.0)
#f
> (array? 1)
#f

However, in 1.9.6:

> (array? 1.0)
#t
> (array? 1)
#f

This breaks generalized-vector?, because it depends on scm_is_array():

> (generalized-vector? 1)
#f
> (generalized-vector? 1.0)
ERROR: Wrong type (expecting string): 1.0

I think this is a bug and the behavior of 1.8.7 should be kept, i.e.  
(array? 1.0) should be false. In fact, I have code that depends on  
(generalized-vector? 1.0) being false. But scm_is_array() calls  
scm_i_array_implementation_for_obj() and I don't understand that  
function.
