The compiler doesn't know that f's return value is unknown to
the rest of the world, because f isn't marked pure.
And, indeed, make f pure and it just works: int[] f() pure

Awesome!

Just a little newbie aha moment I'd like to share.
I was about to post this:
int[] f() {return [1, 2, 3];}
As far as I understand, f returns a fresh array on each call,
and therefore, it should be safe to store the result in an
immutable variable.
Unfortunately, this fails: immutable v = f
Ok, I did a bit more reading of TDPL and decided to go with the
following pattern:
synchronized class A{
private string[] _values;
void setValue(size_t i, string val) {_values[i] = val;}
string getValue(size_t i) const {return _values[i];}
}
Works fine, my problem solved :) Ag
Marco Leise:
This is "just" a syntax ambiguity. a[] takes the complete
slice of the array 'a'. And a dynamic array in D is a slice.
So if you use a or a[] in an expression doesn't make much of a
difference.
Yet in D the only accepted syntax to perform a vector op sum is
to use add square brac

Hi All,
I'm getting myself confused with thread-safety and locking. I
have a class something like the following small example:
class A{
private string[] _values;
void setValue(size_t i, string val) {_values[i] = val;}
string getValue(size_t i) conts {return _values[i];}
