This is true for only a few cases.  Mostly the names are compatible, but
some of the naming conventions needed changing... 

For example:

We have used type for the name of the data type in a numeric array.  But,
this can be confusing because type refers to the kind of Python object 
and all arrays are the same kind of python object.  In addition, it is 
natural to use the type= keyword in array constructors, but this then 
blocks the use of that builtin for the function it is used with.  Of 
course typecode was previously chosen by Numeric, but now the types are 
not codes (they are really type objects).  Thus,  I have been calling 
type (dtype) in the new scipy.base.  The alternative is to keep the name 
type (eliminate the use of typecode, and rename python's type function 
to pytype within scipy).

It could easily be changed if that is a real problem.    Because of the 
signficantly different usage of types in the new system, it is helpful 
to have a different name (dtype).    But, I could be persuaded to use 
the word type and rename Python's type to pytype.
