Potential solutions

Closure allocations

CL01: Fixable by manually stack-allocating closure

  A delegate is passed to some function which stores this delegate and
  therefore correctly doesn't mark the parameter as scope. However,
  the lifetime of the stored delegate is still limited to the current
  function (e.g. it's stored in a struct instance, but on the stack).

  Can be fixed by creating a static struct{T... members; void
  doSomething(){access members}} instance on stack and passing
  &stackvar.doSomething as delegate.

CL02: Using delegates to add state to ranges

  ----
  return iota(dim).
    filter!(i => ptr[i])().
    map!(i => BitsSet!size_t(ptr[i], i * bitsPerSizeT))().
    joiner();
  ----
  This code adds state to ranges without declaring a new type: the ptr
  variable is not accessible and needs to be move into a closure.
  Declaring a custom range type is a solution, but not
  straightforward: If the ptr field is moved into the range a closure
  is not necessary. But if the range is copied, it's address changes
  and the delegate passed to map is now invalid.

CL03: Functions taking delegates as generic parameters

  receiveTimeout,receive,formattedWrite accept different types,
  including delegates. The delegates can all be scope to avoid the
  allocation but is void foo(T)(scope T) a good idea? The alternative
  is probably making an overload for delegates with scope attribute.

  (The result is that all functions calling receiveTimeout,... with a
  delegate allocate a closure)

CL04: Solvable with manual memory management

  Some specific functions can't be easily fixed, but the delegates
  they create have a well defined lifetime (for example spawn creates
  a delegate which is only needed at the startup of a new thread, it's
  never used again). These could be malloc+freed.

CL05: Design issue

  These functions generally create a delegate using variables passed
  in as parameters. There's no way to avoid closures here. Although
  manual allocation is an possible, the lifetime is undefined and can
  only be managed by the GC.

CL06: Other

  Two cases can be fixed by moving a buffer into a struct or moving a
  function out of a member function into it's surrounding class.

Labeled data

Here are the results based on the compiler's report (building Phobos unittests with -vgc flag of DMD).

For templates only code that is _instantiated_ by unittests build is accounted for (~ all covered code).

The tool used to post-process -vgc output can be found here, it's not tied to Phobos and should work with any github-based project (to be extended).
