If expr represents a tuple, we (Andrei and I) were thinking about the
syntax:
auto (a, b, c, d) = expr;
being equivalent to:
auto t = expr; auto a = t[0]; auto b = t[1]; auto c = t[2 .. $];
You can also do this with arrays, such that:
float[3] xyz;
auto (x, y, z) = xyz;
The Lithpers among you will notice that this essentially provides a
handy car,cdr shortcut for tuples and arrays:
auto (car, cdr) = expr;
Python 3 uses:
car, *cdr = expr
a, *b, c = [1,2,3,4,5] # leaves a=1, b=[2,3,4], c=5
I would like D to have
(car, cdr...) = expr
(a, b..., c) = [1,2,3,4,5]
for the equivalent.
Our varargs syntax is b..., theirs is *b. So it mirrors a bit, there. :-)
Excellent idea!
