I have never heard of any programming system anywhere that accepts such
a syntax for integers (assuming it distinguishes integers from other
numbers at all).  I'm not excited about being the first.  Why does this
error surprise you?  It doesn't seem particularly different from arguing
that 1.000 should be considered an integer, which strikes me as a
seriously bad idea.
