let's assume I have
> class C {
> static string foo() { writeln("got called!"); //.... }
> }
then I want to cache foo at some point:
> import std.algorithm;
> auto v = cache(c.foo);
I call do:
> for(int i = 0; i <10; i++) {
> writeln(v);
> }
then it'll print "got called" only once, which is what I want
but something obvious is how do I get the returned value as a
string?
here's why I'm confused more often than I should: I geeeting to
D's way to do thing and the auto keyword even in documentation
confused me a bit as I'm used to C++/C# world where the
struct/class returned is explicity so I just navigate to
aggregate type's documentation page.
