Note that D provides

     __traits(isRef, Symbol)

which can be used to convenient implement lazy-evaluated 
expressions with free functions. Note that it cannot currently be 
used to check whether `this` was passed as an l-value or r-value 
which prevents the C++-expression-template-pattern from being 
used in operator overloading.
