Does scala have arbitrary operators like Haskell? Looks useless
in D. If you have an operator '+' that should not be pronounced
'plus' you are doing it wrong.
Yes.
a + b
could be set union, logic and, string concatenation. The + is just a
message to the LHS object
or RHS :o).
How come?
"opBinaryRight":
http://dlang.org/operatoroverloading.html
It's a "neat" feature that allows operators being member functions, yet
still resolve to the right hand side if needed. For example:
auto result = 1 + complex(1, 1);
Will compile, and be re-written as:
auto result = complex(1, 1).opBinaryRight!"+"(1);
In contrast, C++ has to resort to non-member friend operators to make
this work.
That's nice.
Of course, it's not needed if you overload "+" for the int type to
receive a complex.
