I don't know about the exact etymology of this term, but my
understanding of it is that it's referring to the translation
of a
higher-level concept to a lower-level implementation, such as
the
translation of a C construct into assembly language, or the
translation
of a C++ construct into C (which the first C++ compilers did).
In the
context of D, it can also be used to describe a particular
syntax that
translates to "simpler" or lower-level primitives, such as:
foreach (i; 0 .. 10) { ... }
translating into:
for (i=0; i < 10; i++) { ... }
Hence the term "lowering" (take a high-level abstraction and
translate
it into a lower-level implementation).

This I have had understood. What I was looking know is where come
from the term because I hadn't saw nobody also Walter/Andrei
using this.
