More int and float attributes

I don't see that.  It looks rather like an incremental improvement to C and
C++ rather than a language influenced by Python.

There's an interesting philosophical difference here.  D is defined as a
"systems programming language".  It is compiled to native machine code,
like C.  In such a case, the programmer necessarily needs to concern
himself with the processor's representation of integers and floats.

Python has a rather different focus.  I certainly use it for system
programming tasks, but in most cases, a Python programmer shouldn't need to
worry about the internal representation of variables.  Look, for example,
at the blurred distinction between integers and long integers.

I'm not arguing for or against the proposal, but I suspect these properties
would be rarely used.
