Here's a couple of annoying problems I encounter quite often with D's
properties. Would having some form of property syntax fix them?
1) Array extensions:
class Person {
string name_;
string name() {
return name_;
}
}
auto person = getPerson();
auto firstAndLast = person.name.split(' ');
The above line currently requires parentheses after 'name' to compile.
This one is weird. After defining getPerson() I was able to rewrite the
last line into this and make it compile:
auto firstAndLast = split(person.name," ");
Yes, that's D's special array syntax, where free functions can be called
as if they were "methods" of an array.
Note that you need qoutes, not just ' '.
My mistake.
But even
auto firstAndLast = person.name.split(" ");
does not compile.
main2.d(36): Error: function expected before (), not
split(person.name()) of type immutable(char)[][]
This is probably a compiler bug.
This is my point. The compiler can't tell that "name" is a property, so
it expects parentheses "name()" to work. That's the problem.
I don't think property syntax is truly necessary for this example. You
are fortunate enough to be using strings, which are passed by reference.
Sorry, I don't see how this statement is relevant at all.
