Issue ID: 24541
Summary: cartesianProduct should have length for finite ranges
Product: D
Version: D2
Hardware: All
OS: All
Status: NEW
Severity: enhancement
Priority: P4
Component: phobos
Assignee: [email protected]
Reporter: [email protected]
Does not compile:
import std.algorithm.setops;
assert(cartesianProduct([1, 2], [3, 4]).length == 4);
Currently the code does:
return joiner(map!((ElementType!R1 a) => zip(repeat(a), range2.save))
(range1));
