Issue ID: 21260
Summary: Constraints on user code are private, so user cannot
check them or understand what they do
Product: D
Version: D2
Hardware: All
OS: All
Status: NEW
Severity: major
Priority: P1
Component: phobos
Assignee: [email protected]
Reporter: [email protected]
Example:
https://dlang.org/library/std/algorithm/iteration/each.each.html
isForeachIterable and isRangeIterable are private and rather complex. They are
neither documented, nor accessible to user code. The user's only chance is
peruse the source code or "build and pray".
All constraints on public-visible code should have public visibility.
