I'm formulating a treatise on why delete should be dropped for removing 
elements from AAs, and this is making it easier than I'd expected. ;)

Doesn't it have to be a reference or pointer to something allocated using 
'new' (aside from the AA usage)? I'm not exactly sure what is 'delete'able 
and what isn't.

I believe because the value is being written to. E.g. when it is a
pointer it gets nulled out.

[though that's probably not what Matthew wants to hear from me. i
apparently don't get the vague hint but seeing this Matthew might want
to explain something to dumbasses such as myself]

[I should have probably considered posting the whole message in the
subject line though]

So the reference can be nulled out. You won't have to write:

    delete p;
    p = null;

which is a common C++ idiom.

So would it be possible to change the D behaviour such that if the coder
used a lvalue, D would null it out, otherwise if the coder did not use an
lvalue then D would not attempt to null it out.

Also, this is the sort of thing that needs to be explicitly documented in
the official docs.

Gotcha. (That just adds grist to my mill, however, ....)

Matthew this may seem like a pretty dumb question, but what does RHS stand for?
I'm thinking that it stands for "Right Hand Side."  

Thanks in advance.
