I believe people should not be overly afraid of expression templates. In
C++ they are ugly because the whole template system is ugly. In
principle they are a tremendously powerful concept that should
definitely be supported in D as well as possible.

When I say that there should be support for array expressions that does
not rely on expression templates, that is only because I believe that
arrays are crucial enough for the language to justify this special
treatment.
