           Summary: Documentation for creating a class on the stack is
                    unintuitive
           Product: D
           Version: unspecified
          Platform: All
               URL: http://www.digitalmars.com/d/1.0/memory.html#stackclass
        OS/Version: All
            Status: NEW
          Keywords: spec
          Severity: normal
          Priority: P2

When I first read the spec on creating a class on the stack, I thought the 3rd
rule meant that I could not instantiate a stack class with parameters to the
constructor.  After asking the question to digitalmars.D.learn, I have learned
that it means the new function cannot have parameters.

Since almost everyone does not use new parameters, and usually uses constructor
parameters, it would be good to clarify that the rule specifically means new
parameters and not constructor parameters.  e.g.:

  * use new with no arguments (constructor arguments are allowed)

And it would be even clearer if there were more examples:

class C { ... }

scope c = new C();      // c is allocated on the stack
scope c2 = new C(5);    // allocated on stack
scope c3 = new(5) C();  // allocated by a custom allocator
