One thing to keep in mind is that structs are passed by value, so
this foreach would be operating on a copy of the entry. So your
setting the value to 42 would have no effect.
Instead you would need "foreach(ref entry; entries)" in order to
have the change take effect (regardless of whether or not you use
std.algorithm).
