[Issue 9009] allow foreach without identifier

[via Digitalmars-d-bugs]

--- Comment #8 from Nick Treleaven <ntrel-public at yahoo.co.uk> ---
Just to note that a related issue is:

foreach (i, Unused; ...)

This may be more common than the foreach (Unused; ...) case - see:

http://forum.dlang.org/post/lnhelg$g01$1@digitalmars.com

A possible solution for both is to use '__' for the unused variable, but the
language enforces that __ is never used and is allowed to shadow:

Note that __ is already a reserved identifier.
