Of all of the differences between C and D, the one which I have
the most difficulty adapting to is null being lowercase. Does
anyone know why this decision was made?
Keep in mind that strictly speeking, "NULL" != "null":
NULL is a C macro that expands to 0.
null is a D keyword that cannot be implicitly cast to an integer.
This is a source of bugs:
//----
void foo(int);
void foo(int*);
//----
in C++:
foo(NULL); //Calls "void foo(int)"
in D:
foo(null); //Calls "void foo(int*)"
Having code that is valid in both C++ and D, but having a
different behavior would be VERY bad.

BTW, you can be thankful that it is *just* "null", because what
it really is C++11's "null_ptr". Which is worst.
